I have the Ping G400 Sf Tec. Why Ping came out with the G400 which is 445 cc's in the Regular, Sf Tec and LS Tec and then came out a few months later with the G400 Max (460 cc) is beyond me. The 445 cc versions are ~9200 MOI and the G400 Max is ~ 9900 MOI.
They should've just did the G400 Max in Regular, Sf Tec and LS Tec. Several Pros are playing the Ping G400, both the 445 cc and the Max. Seems if you don't want the Sf Tec or LS Tec versions then why not get the G400 Max with it's 9900 MOI?
BTW, the best way to gain a few extra yards is to move up to a short tee box. 😉
