I'll vote Pro 5.0, but i've never 'owned' any of the 3. I've driven the Pro though, and they're worlds apart from stockers. The arm actually feels LONG to me, 'cause i've got a funky little arm on my Tremec shifter....take your stock arm and cut it right where the first bend starts from the very bottom, then cut the top part about 1/2 inch down from the threads where the ball goes on, then weld the 2 together and you've got my shifter arm. It's a loner from a friend since i didnt have the cash for a shifter when i got my Tremec, but i've actually grown on it a lot after driving with it. It's about the shortest throw i've ever driven but you've gotta reach for it more than i'd prefer.
