I agree to get the bike that feels right... you can always take the Trek to your LBS for service etc... many LBS consider it a compliment that you trust THEM with your other brand bike to do all the repair stuff... I ride a Litespeed, but all my maintenance is done by my local Trek Store!
I tried the WSD Trek and it just didn't work for me... they were very cool about it and the manager still gives me a hug even when I come in with my LS...
There is a fine line between "hobby" and "mental illness".
