Getting ready to upgrade my irons to try and help with my game. I'm about 60 to 70% on my irons, as far as good, solid contact. I'm going to spend anywhere from 400 to 700 on the new set. I've demo'ed the X-20's, Big Bertha's, Cobra Fp's, and Nike Slingshot a couple of times each. First time, swore I was getting the Cobra's(felt the best), second time the X-20's(felt the best). Any thoughts on which of these sets my be my best choice as far as forgiveness and growth as I'm probably gonna have these for a long time. Don't really like the feel of hybrid irons either.
