Tomcat, thanks for the feedback regarding the Max v. BB. I'm currently trying out a Max and BB 7 Iron to decide which will fit. Upgrading from Taylormade Rocketbladez.Also, when being fit for the Mav Max, I was told that the current Berthas are the closest iron to the Max that are in their current catalogue. If you're talking about going from the BB to Mav standard or Mav Pro, unfortunately, I can't speak about those irons.
