slmpickins: So the 38yd shot I tried shooting it for 45yds to back up, stopped instead of backup because it's a partial swing from a 60yd iron? Only shoot for a 50yd shot so it will back up from a full swing from a 60yd iron?
That is correct - the correct 'shot' to make would be using 64 degree Cleveland (rated at 60 yards) using :"Punch" mode (rated 50 yards) at about 80% power - backspin or topspin optional, and factoring lie, wind and elevation. Personally I use backspin on partial punch shots with this club from green-side bunkers most of the time.
The ONLY scenario where you COULD attempt what you were trying to do is if the shot distance were say 50 yards or a bit longer - you COULD apply full shot, full backspin, have it land past the hole, and spin back. But WHY would you when it is a simple full punch shot with the same club, predictable distance, stops on a dime?? The punch shot at 50 yards you can count on virtually every time. The full bs, full shot is completely unpredictable - you MIGHT get it close, but you also could end up anywhere between well past the hole or you could land past the hole and spin back off the green!!
