Bunch of should-i's:

Should I sell the used Dura-Ace 7710 crankset w/bb (got it for $200), profit, and get something cheaper (i.e. omniums) or just run them on my new Soma rush build?

Should I build up my Soma rush and then sell the Mark V or have it do duty as a singlespeeder?

Should I use the IRO wheelset on the Soma rush or get the Wabi wheelset (or something else)?

Should I get 28c or 25c Panaracer T-servs? I weight about 160lbs.
