Do others find that when you grip strong there is shaft lean at setup? Doesn't that deloft the club and cause a lower ball flight? I find that if I grip weak the ball moves forward in my stance and I get a higher ball flight.
Like what Mr. D said about not shortening more than about a half inch and adding about a couple of grams to the head. Stripped off excessive lead tape and reapplied about 4 inches to a 45 inch driver and 3 inches to my 42.5 inch 4-wood. Feels great!
