I have been shooting a CD34 and CD Turbo side by side this winter and spring. Both are at 28.5" so the turbo is in a more forgiving end of the cam. Both set between 71 and 72 lbs. Turbo shoots 15-17fps faster with the same arrow if I'm remembering right.
I find the difference in draw cycle to be negligible. I have to shoot them side by side to tell - it is there, but it really isn't all that much different for me. The valley on the Turbo IS shorter, and I think if you are too long on draw length then the Turbo really wants to roll over and go on you. Getting my draw length to the point where I wasn't stretched out, leaning back at all, any of that - made a big difference.
I think Phil Mendoza made a comment about the Defiant Turbo with the DFX cams in one of his video threads here - putting the speeds in the middle of the two. Shorter brace height of the Turbo, Draw and valley of the DFX...
