SmillerTim3: Also if your club says 150yds is it's max distance, when you hit the ball off the fairway clean at 75% make the ball travel 75% of 150, not 50%, not 60%, it's 75%, please make this accurate so you can actually judge the distances you are hitting the ball at.
Of course, for years, what I've been asking for is for other clubs to use. I mean, instead of having to use my 150 yard iron at 75%, wouldn't be great to have a club rated for about 110-115 yards? If it's 120, that's fine as well. I'll just take a little off when I hit it.
Boy, that would make the game a lot easier.
Edit:
But here's some unsolicited advice. If you find it helpful, great! If not, ignore. First, you're in a great CC. If you're not already doing so, ask for some help from the people there. They'll be more than willing to help you out. And they'll give you great advice and help.
Second, if you want to stop the ball on the green, you're going to need to do some upgrades to your irons and wedges.
For irons, you'll need a high trajectory set with some spin. Since you're already at Level 84, you might as well wait until you level up. The Callaways at Level 85 look really good. You should also think about upgrading your wedges. Moreover, you should be carrying 3 wedges (56, 60, and 64 degree).
Finally, after you do some equipment upgrades, consider investing in a bit better ball. The best value ball (IMO) is the Callaway Soft Chrome (Level 33+). If you were to do those upgrades, it would totally transform your game. I guarantee it.
By the way, I cannot think of a single reason why I would ever hit an iron (i.e. 3 though 9) at less than 90%. I really can't think of a situation where I would do that. Between 90% to 100% the irons and wedges are fairly linear. Below that, as you found out, they're not. Nevertheless, I just can't come up with a reason why I would hit at 75% an iron rated at 150 yards. There's no reason.
