The Pro5.0 with the ws6store short stick moves things closer to the passenger side of the vehicle. Noticeable at first but easy to get used to. The stick that comes with the Pro5.0 is close to stock, but too tall for my tastes. I currently have one in my car, never went to the wrong gate.
The Ripper keeps it closer to the stock location, but is as long of a handle as stock. Also the handle can not be changed as it is all one piece from knob to where it moves the cup in the transmission. - Had one in my LT1, but it felt like you were swinging a bat and I watched someone perform a 3-2 shift at the top of 3rd because it felt like 4th.
I definitely recommend getting an aftermarket shifter, the centering springs help alot, but its the travel stops that allow you to shift hard and not bend/break things.
