Great stick. I have the 460 as well (the titanium not composit). It is the only club in my bag with an R shaft. Everything else is S. Slow back swing and big finish. Must get those hands out there. The 9.5 will not pose a problem. Because the head is larger than my earlier Mizuno 350 Blue Rage I find it better to align the ball further to the left than the standard.
This club rock the ball. Best of Luck.
