I'm looking at buying new clubs and mixing up my iron set. PW-6 in the AP2 and 5-4 in the T-MB. The reason for mixing things up is that I've got a reducing gap in my irons as I go up in length. The T-MB's have 1 degree stronger lofts and reportedly have 3-4% more ball speed off the face than the AP2s. They also launch a little higher which I like with the longer irons. I'm wondering if I should go strong on my AP2 lofts, at least in the 7 & 6 irons in order to maintain more consistent gaps.
