I have the skunk2 knob, but because of the height of the knob i would often grind gears shifting into 5th gear by releasing the clutch too early, and because the throw into 5th gear was far away.(i'm 5'6" so my arms are kinda short). So i started using the Blitz shiftknob and being a ball shape, it helped out alot. I ordered the T1R quick shifter last night, so hopefully i can go back to the skunk2 knob(i miss the weighted feel)
