I keep the counterweight off because of the 'clunk-clunk' feel that it creates. The best knob I've had on the car is a heavily-weighted Razo leather palm grip, which was excellent. (The heavier the knob, the more 'directional' your throws become.) But I'll stick with the SVT-logoed knob on the car now because it just looks too good to not use.
