I agree its all about yhe angle of attack and where you're catching the ball. Handicap has nothing to do with spin like other posts have said . also with full wedge shots if people arent getting spin it could be from a low swing speed. You need to hit that thing with some power to make it spin. Why do you think pros prefer full club shots instead of 3 quarter wedges cause they can't get the same amount of spin. I'm a very good pool player and its a similar concept on getting the ball to draw back. Natural momentum is a ball rolling forward you're going against that so the more force the more spin.
