I never tried the Pro 5.0, but I liked the Ripper good enough. From most threads i've seen about it, most people would choose the Pro 5.0 with Lou's Short Stick over a Ripper, but everyone usually says they're on the same level. The 2-3 shift on the Ripper is real nice... All the shifts feel good, and I believe there are adjustable stops.

You really can't go wrong with either, but if you get the Pro 5.0, get Lou's Short Stick. The Ripper is already lower and angled back a bit.
