Alex, I've been here for a while but am not one of the top players. From reading the forums, I have a head full of information and only lack the ability to execute to achieve lower scores.
Looking at your stats, it looks like you've been away for a while.
Just a reminder, this is entertainment ONLY, you cannot make a living here but you sure can dump a pot-load of money for gear! Yes, your gear could be improved and only you can decide how much you want to spend.
Without regard to cost, here are a few considerations:
1). Ball - pick one and stick with it! When you "map" your clubs, the data that you collect depends upon 3 factors: the club, the ball & the "ding". Why waste money mapping clubs with 600 credit balls if you aren't going to play with them on a daily basis?
Some of the best players here recommend the Callaway L33 until you want to spend a paycheck or upper level balls. The Cally 33 is pretty darned consistent and only costs 250 credits.
2.) Meter speed - you already know that the "ding" is gold. If all of your clubs have the same meter speed, (theoretically) it should be easier to hit the "ding" consistently. The possible exception here is the putter as it is rare to use a full (100%) swing in the green.
3.) Drive for show ------ Yes, it's nice to put the ball WAY down the fairway - but your "short game" is the source of low scores. Irons and wedges should have consistent 'distance' spreads between clubs.
a). The Cleveland wedges (64, 60 and 56 degree clubs) publish distances of 60, 75 and 90 yards and they are pretty darned close to what you'll see them play. They have a meter speed of 3.5 - more on this later.
b). The L32 TaylorMade R11 irons will serve you well until you reach over level 60 (where the MUCH better irons live). The R-11's have a meter speed of 3.5.
4.) Your 3 Wood is OK for quite a while - it is rated at 227 yards and you will not be eligible for woods with much more distance for quite a while. Meter speed is 3.5.
5.) I would recommend that you hold onto your current driver until Level 48 when you can buy the TaylorMade R1. Yes, it has the same 3.5 meter, but its rated distance, forgiveness, precision are all good enough to take you up many levels.
Others may recommend other equipment, and that's fine with me, but the truth of the matter is that practice and playing experience will make the biggest difference in your game.
Good luck!
