med. traj. clubs vs. med./high traj. vs. high traj. differences

  Just wondering what people have learned in adjusting calculations for this under the radar issue. Height adjustment shifts for all lengths, wind effect differences from lower or higher flight, ability to stop on greens, etc..

  Since I've changed to the full set of TM Rocketballs, the med. trajectory has played some tricks on all my calculations.Sometimes long sometimes short, more wind less wind, bs, no spin. All over the place. As in real life getting much better with short irons but those adjustments that i used to carry up the ladder to the long irons has dramatically shifted

  I myself can only add that the ability to stop the ball has become less of a guarantee, especially once into the mid irons.

  Seems like i had to add more yardage for full BS. Was (for full shots) 2-3 added for long irons and 5-6 for short. Now I'm close to 3-5 for long and 6-8 for short irons.

  Even in chipping this slight variance leads towards going past the pin more often and overplaying the break from unintentioned extra length.

  Have gotten pretty good with 1-3 yard rollout always givin on 8,9,PW.  Subtract 2 yds from final calc and let it roll up. Now of course if using any ball with over 3 1/2 spin attribute will stop completely or even come back, but a 3 spin ball and a 3 spin short iron with med. trajectory should generally tend to roll 1-3 yds when landing with FULL backspin on it from the fairway and 2-4 from 10-20%lie in first cut.

  Please help fill in the massive gaps in amounts of data that a thread like this could amount to. I know i could benefit.

  Sry none of u guys could offer me anything constructive. Luckily the real players on this game msged me directly and let me know the things I was looking for all along. But hey thx for jackin my thread.

  My advice, and try not to take it as crass, is to start playing golf and stop playing math.

   Look, I get that lots of people are into these massively precise computations and I'm not saying don't work on improving your game, but the precision desired in the formulas will just frustrate you over the long haul when it "doesn't work out".

  Personally, I've mapped my clubs to know their yardages, so I know within a small range what they should do on a given shot, and then I know how to adjust for wind based simply on experience, past notes, etc.  Putting is where I put in the most work b/c it'll shave the most strokes off, but none of the computations you're talking about really apply there.  

  Just learn the clubs and play the game - - no one is going to A) Commend you for acknowledging that your clubs are different, or B) Give you a magic hole-out formula that works with them.

  i'm one of those who do the math on every approach shot to the green .. elevation, wind & b/spin .. it works perfectly for me, but that is my nature .. i use high lofted clubs (G20's) cause they have substantially more stopping power than med trajectory clubs, but again, that is the nature of my game .. my aim on apprach shots is to put the ball on top of the hole and stop it where it touches down .. if that's what you wanna do, forget about the med tracjectory clubs .. the Driver is ok though, use it myself

  Going from med/high loft of the Raptures to the high loft G20's was a complete surprise. And for me not a nice surprise, I suck with them. I do just fine with the high loft Cleveland wedges (I love 'em) but the irons are just a different story altogether, at least for me.

  I like the comment about thinking golf not math. A certain amount of math is inevitable, but sometimes when trying to decide the effective length of the shot, and find myself unsure, instead of thinking of precise math I think what would be the right club for the shot.

  i started with the backspin game using the raptures & i found i could use the exact same yardage adj's for backspin using the G20,s, except the G20's provides more of it .. the faster mtr and less forgiveness takes some getting used to, but in the end they worth it .. i will only trade them in for the lvl 83 G20's .. so it really comes down to ur approach to the game ..

  Chris,

  I play the math game as well and the high trajectory is the only way to go. I used the Raptures up until L59 when I switched to the G20's. Loved them like crazy. They actually stopped on the greens. As soon as I made L83 I got the entire upper G20 set. They're great!!! Sold back the 3 Hybrid and it was still less credits then getting the Driver, 3 Wood and Irons separately. After less than a week I'm shooting lower scores then ever. You'll love the L83 G20's if your very happy with the L59 G20's now.

  I'm a little jealous that you guys have got the G20's down :)

  I'm a pretty lousy CTTH player but with the G20's I bomb completely.

  Maybe it's because I hardly ever use spin and you need to know how to use spin with the higher level irons. And with the high loft irons--longer than the wedges (I don't seem to have a problem with the high loft wedges)--you really have to know how to adjust for wind. With the Raptures I just guesstimate and do ok. I have a lot of fun playing with the Raptures, it's going to be a while before upgrading is a real issue so I'll cross that bridge when I get there, I guess. But it would have been sweet to have been thrilled with the G20's right out of the box.

  Hey Cerino .. u really got me salivating over those Lvl 83 G20's now .. can't wait to get there .. i'm curious about the fractionally higher mtr speed versus fractionally more forgiveness & precision .. i'm hoping for a seamless transition, but i'll do couple of practise rounds with them 1st ..

  Nyctc7 .. Cerino is absolutely right .. if u wanna consistently put the ball 0-3yds from the hole on approach, u gotta go with lofted clubs with stopping power .. G20's are great for this .. i had to practise alot to get the yardages right, lotsa practise games played under various conditions .. u just gotta practise practise practise .. well worthe the effort

  I'll give an example of my math for an approach shot .. keep in my mind that not everyone's methodology on doing the math is the same, but this is just a guideline that u can use & then go out there, try it and refine it to suit your game.

  Example: 150yd approach, wind 10mph directly from the front, elevation 12ft ..

  1. elevation .. i add 4yds (3ft = 1yd)

  2. wind .. anything 10mph & under i'll add half the wind's velocity in yrd'ge .. so i add 5yrds here

  3. bacspin takes distance off the shot .. on this distance i add 6yds to the shot (various distances = various yds added for backspin .. i will list my ydg adjmts for backspin after this example)

  So the total distance for this shot: 150yds + 4yds + 5yds + 6yds = 165yds

  Now u just gotta ding the shot .. lol .. thats where things go astray sometimes, but if u ding or close to it, u should end up close to the hole for a 2-7ft put.

  Keep in mind, this methodology workd for me and i had to work it out systematically over many a practise round

  My yrdge's for backspin as follows (what i add for backspin using G20's & Nike balls) :

  1. 40 - 89 yds .. add 4 yds

  2. 90 - 130 yds .. add 5 yds

  3. 131 - 169 yds .. add 6 yds

  4. 170yds + .. add 7 yds

  Gud luck to u .. try iy out & see how it works for you .. for best results i recommend Nike balls .. but u could get decent results with Callaways also .. dump the Wgt balls .. they's get u nowhere if u use them

  2. wind .. anything 10mph & under i'll add half the wind's velocity in yrd'ge .. so i add 5yrds here

  the factor for the wind is is a bit more than just halving it. The formula is (distance x wind factor percentage) +/- distance = shot

  for example lets say you have 218 yds to the green and a 10 mph wind in your face

  that would be (218 x 4%) + 218 = 235 for your club selection if it were at your back it would be 201 yd club. with the legend nike ball you have to add 4 yds to any club on the distance. The key is knowing the percentages and it has taken me a while to figure them out. You are close though on a factor of a 5 mph wind, but it would be 4 yds, not exactly half of 10.

  5 mph would be 2%, 6 mph is about 2.66%, 7 mph is 3% and so on. I have fine tuned it to where I have for example 9 mph is 3.66% all the way up to a 20 mph wind is 8%

  Thanks chris5214, I have been very impressed so far by the willingness and courtesy of the more experienced players to give good advice and encouragement to newcomers like myself (though I registered in December 2011, I only actually started playing  5 weeks ago). 

  Shot a 71 on Olympic yesterday (with the Raptures) but not the tournament speed greens. Considering I hit a tree on two holes I think I did well. This is a course where you can really see how you need to be good with the fairway woods and the longest irons 200+ yds, especially once you start hitting from the longer tees! At that point I can see how the Raptures wouldn't cut it anymore, unless they offer a version above L48, which I tend to doubt as aren't they in real life considered game improvement clubs, not clubs once you become a great player.

  Crosswind affects the G20's much more than the Raptures, I think. Right now with med/high traj. I probably move the pointer one to a few yards when at or below 10mph, depending on the angle of the wind and how far the shot is. Around 15 mph significantly more. Above 15mph move the pointer AND hit the shot early/late depending on wind direction (if the direction is only slightly to the left or right, just move the pointer) . I also find with the Raptures that below 15mph a direct crosswind (direct meaning the indicator is at 90 or 270 degrees) doesn't significantly affect my distance calculation (even though you'd think it would). Above 15mph I get confused as I've both had yards lost or gained with a direct crosswind.

  Any comments about crosswind , especially blowing directly left or right, with the high loft G20's? 

   

  Again, thanks!
