IMO with your fixed gear, you should always put a brake if you're riding the streets, who cares if people talk crap for having a brake. You'll have the same connection with the bike even with a brake, on and off the road. You don't have to use it if you feel comfortable stopping without one, but it's best to leave it on the bike for situations in which you may need one.
