I don't know, and right now everything I ride feels great since I'm just happy to be on a bike again.

What I do know is this,
-I want the bike to be able to be ridden single speed or fixed and to have rear and front brakes
-I want the frame to be decent enough to justify potential upgrades, in case have to make some compromises building it initially.
-I'd like to put fenders and maybe a rack, since this will handle some errands.
-It would be great to like the color, I lean towards the more retro subdued hues. Maybe this is why I don't like the current Cross Check
-I am over-thinking everything, it's what I do
