You're not brakeless yet, what is holding you back? Nothing is holding me back, I enjoy my breaks. When I was in high school I had my brakes off for a couple years and it was great, last year I took them off for six months and I had a good time as well, but at the moment I am having fun with them.
Does your bike rattle anywhere? Do you care? My bike does not rattle, and if it does it will drive me crazy.
Do the colors have to match? They don't really have to match, but a good color combo definitely can add to the steez.
Are you very weight conscious? No not really, everything on my bike is stock, couldn't tell you how much it weighs.
