I don't know if this has been brought up before, but will a fork brace help with tar snakes? I don't know if it is the weight of the bike, the tires, or lack of a fork brace, but my F6B feels especially squirrely when I hit the tar snakes in a curve. The F6B is about 200 pounds heavier than the next heaviest bike I ever owned, so maybe it is just the nature of the beast.
