That Helim has been a problem child for Mathews this yr. Seems like they went with cheaper components on it and are running into problems here and there. I went in one bow shop that the bow tech was loving it...best bow they ever made. A month later and he'd already replaced several things on it and last time I was there, was talking about going back to a Z7 Xtreme.
I think it's the "cheapest" looking bow they've ever made! I am a HUGE Mathews fan, it the only bow I'll ever own, but the helim looks like corners were cut, price stayed the same and to justify it they promote it as a light weight bow!
