hyena64: My math is by the seat of my pants. KISS. That's my method. The less thinking the better. And for me, it eases the pain as well; the not thinking that is. I await your wrath.
No wrath here, that's just playing by feel, which I do too. If you play this game long enough you get mental memory much like athletes get muscle memory from doing something over and over. It gets to the point where you look at the yardage, wind and elevation and get a "feel" for what the shot is going to do. Get in the right church with some simple math, grab the club you know is right, sense how the wind is going to affect the shot and aim accordingly. It doesn't have to be exact, just close. (Holing a fairway approach is an accident.) Knowing your clubs is imperative.
What I like best about playing this way is the expectations don't get crushed because my slide rule said aim here and hit to this line and you wind up someplace else other than where you expected the shot to go. Deviation becomes part of the game naturally and you never know if it was your mishit or the deviation that caused the result. Just go find the ball and do it all over again. Lot less aggravation and with a WGT ball you're always near where you expect to be. :-)
