I want to get rid of my cruddy shimano drivetrain and replace it with a Sram system. I have some experience with 9.0 half pipe shifters. I liked the fact that I could shift in either direction as many shifts as I wanted, and it was so much more accurate than my current XT/STI setup. The only thing I didn't like was the tendency for me to accidently shift my half pipes. I think most of those problems would be taken care of with a set of shorties.... but I am intrigued by the X.9 trigger shifters too. What I'm wondering is if they give you the freedom to shift up or down as many clicks as you want, like the grip shifts do?
