I just got my performX 3D and IMHO it is the best target bow I have shot to date. I have not shot the echelon or even held on to one. I love the grip on the PX3D and how adjustable it is in terms of draw length and letoff. It draws nice, holds extremely well, and I have seen noticeable improvements in my scores and X count over my evolve 35 which I was shooting previously. Honestly if I was designing a bow it is exactly what I would design. Only thing I would change is I would get rid of the LAS system. It is not needed and IMO is one more thing that could possibly go wrong in a tournament.
