I recently put the 714 MBs in my bag, only a selected few, 7-PW. I have noticed that i am losing about half a clubs distance with the MB's as opposed to my 714 AP2s. I went in to a local golf shop and started hitting balls, the RPM rate for my MBs was a 1000 more on average as opposed to my AP2. I only took my 7 irons in with me to hit but i feel like this is the same for all of the MBs. What would be the reasoning for this, why are the MBs producing so much more spin. I generally hit the ball where i am supposed to on the face of the club, see attached.
