As ususal, Dave you did a fantastic job covering the main points.
I am not a 29er at this point. Anything that gets me higher off the ground on a mtn bike to me, feels like I have farther to fall. haha...short guy mentality..

I think the Velo swap already went down or is this weekend. That is also a great place to look, as questions and find great deals.
