Ive had the Pro 50 and the Triax I cant see any difference at all, Just be prepared for a little more transmission noise, which happens with all of them. Good luck:beer:
The UPR is supposedly a copy of the Tri-Ax shifter...I've driven one, but feel it is too stiff (offset springs) for my liking...Plus I think the quality of the Tri-Ax is much better than than the UPR model...Its like the old saying...You get what you pay for...IMHO get the Tri-Ax they're really not that expensive...I got mine shipped to my door for $180
