Speaking of low BB... Has anyone ridden that Speedball line at Eastside on one of these bikes?
I'd be curious how a low BB bike feels at those speeds.
Or how would something like the Wave C feel at those speeds...(super high BB)
Don't think there has been too many big wheeled bikes riding Speed Ball.  There is one local there named Patrick who rides a 26".  I never saw him hit Speed Ball though, but not saying he didn't.  
I rode my Model C out there for like 6 laps through main line until I crashed and broke my back and wrist.  For the few runs I did make it through, it was AMAZING! Still haven't won the war in my mind to take another lap out there.  One day though...
I have hit a line at a different Austin spot called 4 Loko.  It is a fast down hill line that ends up in a super tall right hip.  I don't even like to ride my 20" out there anymore because the 24" feels so bad ass.
