I know the clubs are in the validation stage but what is the scuttlebutt on the difference between both.  I currently play the 710 AP2's which I love but recently got on a launch monitor and the MB's brought my spin rate down about 300 and the launch angle down 1.5* and my carry distance increased around 8 yards for my 6 iron.  I was carrying my 6 iron around 170-173 with the AP2's and 178-181 with the MB's which is pretty big for me so therefore I am going to pick up a new set and I am probably going to go back to the 710's unless there is going to be a big difference between the two which I doubt.

Also,  this is a question for a Titleist guy,  how much longer are you able to custom order the 710 MB's, CB's, etc before you will not be able to.

Thanks
