Right now I'd have to pick my 71 Super Sport with a tripple and Suntour 6 speed freewheel. That could change in the next few days when I finish up the 83 Trek 600. Haven't put miles on the 600 yet, but I think I'll like it. I'm glad I don't have to choose, what would I do with my 85 Trek 660. or my other 71 Super Sport, or my 2013 mountain bike or my Coda Comp, or....
