it's either out of tune or your draw length is too long, as stated above. i shoot a Carbon Knight, and yes it will jump on you if you dont hold that back wall solid, but no more than any other bow. just train your muscles to hold back the actual let off weight, because right now your mind is telling you it's going to let go causing you to pull back a lot harder than necessary. you can put your draw stop one peg farther back but i do not recommend doing that because it should have a great valley and solid easily hold able wall if it's tuned and the cams are in sync.
Bowtech I got mine not to long ago. Amazing bow. Could not have asked for a better bow at this price. Shoots straight, very quite, and its lighter than a feather. Bowtech continues to change the way bows are made, while many will say that Hoyt or Mathews is better, Bowtech is providing much more innovative products.
I don't know about that last statement. My first bow was a Diamond, and I certainly looked at the bowtechs available at the time, but I ended up getting a z7, and later upgrading to a Helim. As for the innovation of bowtech, I may be wrong, but I believe Hoyt was the first one to really pioneer the carbon bow with their carbon elements. The Hoyts certainly have a much higher visual appeal than the bowtechs, and from my admittedly limited experience, their carbon bows shot more comfortably and more accurately than the bowtech by a significant margin. Bowtech has made some really nice speed bows from what I have seen, but to me they always felt like a really harsh draw cycle.
Hoyt didn't pioneer carbon risers. Engineers at Prince (the tennis racket company) did. They then brought it to many manufacturers in the archery industry as a fully baked product and sold exclusive licensing rights to the highest bidder once they had already figured the design out and patented it. Look at the patent below and google some of the names on it, that really tells you who's behind the carbon technology Hoyt is licensing.
I just meant that Hoyt was the first one to start selling carbon bows (to my knowledge). I am not knocking bowtech, and I can't speak to their RPM or the carbon overdrive, as I have yet to even see one. Just at the time when I shot the bows, the Hoyt carbon element felt better to shoot than the carbon knight. My Helim felt better yet. In another couple of years when I upgrade I fully intend to try out Hoyt, Bowtech, Mathews, and from everything I have been hearing I should check out elite as well. For me whatever shoots the best is the one that I will take home.
