There are several stock options as well as TONS of upcharge models available.  The biggest surprise is the new co-branded diamana whiteboard.  It's not exactly the same as the $200.00 upcharge shaft that you see on the tour but it's very very close.  I was fit for the 910 series with a launch monitor and the stock whiteboard shaft paired with the new head was giving me 12 more yards of carry on solid strikes.  More impressive was the mis-hit difference.  My 909 D3 with a 757 Speeder was about 20 yards shorter than the newer club when I made a poor pass at the ball.  Im looking forward to getting the 910 in Novemeber.  I recomend getting to a fitting center to get launch monitor help in the process.  The numbers don't lie and the adjustability makes having professional help VERY rewarding.  Enjoy the new product.  I know I will!
