The "knob" has nothing to do with the length of the throw, however an adj. short shifter will decrease the distance needed to rip thru the gears faster. The " knob" that you use to grip the shifter is of personal choice. Shorty "ball" type knobs look cool IMO, but having a "tall" knob would however place it closer to the steering wheel via right hand, allowing you to grasp it quicker. Having said this I've gotta go take care of something...:naughty

...Seriously though, Check out the new Honda Civic Si shifter placement...on the dash! Now thats close, still I'd like it on the steering wheel F1 style!
