speaking race wise, what kinda speed control are you running? castle creations has a software program thatll allow you set your own throttle curves, you could use that to lower your top speed as well as the responsiveness of your throttle.

but bashing wise, id go with longhair, at least youve got it when you want it, thats what i do as im not a racer and have busted the adapter off of my esc.
