Meter Speed, Precision, Forgiveness, Ball Characteristics, adjustments for stance and club face all important factors.
I really liked the variable meter speed through the iron set (long irons are harder to hit)
Also maxing out the meter so the reward for ding is greater and the punishment for missing it is as great. Watching the Pros on TV crushing the ball with all their might, when they mishit it it shows.
The only other thing I've read about is changing from the 2 click swing. TrueSwing sounded too easy to rig and a 3 click system didn't show much approval either. It just seems that being able to pull a club back to an exact point in your swing makes the shot a whole lot easier.
My only other thought for now is Drive for show and Putt for Dough. The various diffenences in Tournament Green ( course to course and tier to tier) make an adjustable daily stimp meter (by WGT) seem like a reasonable idea.
Anyway, none of it affects me. I'm still mediocre but still addicted to this wonderful game. Thanks WGT.
