one of the best things I ever learned is that with a SW and PW you can use a putter type stroke to not overpower. It's pretty simple to think of but hard to do. You don't need a full swing just go back and fourth just like a putter. The best thing you can do is go to the range and spend a large bucket on just your wedges. Try to shoot for different spots. Try moving the ball back and fourth in your stance and see what results you get. Practice like you play and play like you practice.
