I have run both the Tri ax and the pro 5.0. BOTH are great pieces of hardware. The only complaints I've had about the Tri ax is the weak feeling handle, but you can get a replacement for it that is stronger, it also has pretty smooth engagement and positive stops. The Pro 5.0 is my preference, but the handle is kindda short. so if your tall like me you have to lean forward a little to reach third and fifth. Its is very notchy almost making a clicking sound when you engage a gear a very positive feeling, the solid feel more than makes up for the short handle, I really should say that the short handle is really only an issue on 94 up stangs. I didn't have this complaint on my fox. The steeda is more comfortable for daily driver, but if you are gonna beat on it go Pro 5.0. But, you can't go wrong with either.
