Just bought a new '11 Slice 4 last month. Its a great bike. You will love it. The Sram components were new to me, as they shift differently than my Shimano on the road bike. Sram seems to shift more abruptly, but right on every time.
Picked up the Slice 4 today! Felt great from the fit to my first ride. It is definitely a better fit for me then the Trek, atleast from a feel/comfort perspective. I am also happy with the SRAM R2C shifters that come on the Slice 4, I found them easier to manage then the traditional ones (I assume this is personal choice).
