The Bang 'Bang-O-Matic'! 460cc of power plus the FAS. FAS stands for Flow Alignment System, and so far as we can tell, it really does direct more energy from club head to ball and with less dispersion.
Bang tells us that most Modern day drivers deliver 78 percent of the proper directional energy toward the ball with a 22 percent dispersion of energy...But with the unique Flow Alignment System, the energy transfer is actually 94 percent directional energy! And this makes for straighter and greater!
The size is 460cc although it looks more like 400cc at address. Bang wanted to optimize the performance and still have it appeal to to players that aren't crazy about huge heads. This is a super premium head.
