kinda nice to have a warranty, and yeah i think the 05 will be a lefty, my friend has a lefty on his rize and loves it, but i prefer the fox on my rush, also the lefty is a pain ot get the wheel off compared to a qr. I'll be movin to a 20mm TA shortly which will be annoying on my roof, but wtill not as bad as a lefty cause at least on most TA you don't need tools. Actually you can change a tire w/o removing the wheel on a lefty, so its really just annoying if you have a fork mount roof rack
as for clearance, the issue isn't the rings so much, u'll smash any bike's rings eventually, solution: bash gaurd, more clearance and i don't have to worry when i do hit, I upped ot a 36t ring also to avoid sacraficing speed. The real issue with a low BB is smackin cranks on stuff, thats when i find myself wantin more clearance, when i'm trying ot clip in in a rock gardin, or when i wanna pedal through bumpy stuff.
