You should always run two brakes on a singlespeed. Not one, not none, two.
I'm currently running FG for the first time, but had originally meant to have it set up as SS. The LBS guy felt bad (it was their mistake) and threw in the freewheel for free (flip hub). I then mentioned the need for an additional brake and he felt one would be OK even on SS.
I tend to agree with Tejano (and you), though. If I do go back to SS, I'll go two brakes.
Thanks for input.
