I had one and ended up selling it ! First of all I only had it about 2 months and the string blew up in my face on a 3D shoot and Mathews would not replace it and blamed it on me ! It ended up bending the cams that needed replaced which Mathews did replace !
I could not get a consistent grip on it so my grouping was all over the place ( didn't like the squared off grip) I was not very confident shooting the bow and never could get the good groups I wanted and it seemed like every time I shot it I had to readjust something so I sold it and went back to Bear bows and the first time I shot my new Kuma 30 all my arrows were touching so I'm very happy with it.
On another note the Triax is very quiet and has a very smooth draw
