Both of those bows will be a pretty good choice. I am not going to say that one is better than the other, just go with the one that you feel is the most comfortable. Lots of guys like a shorter bow vs. a longer bow, so pick the one you like the best, that is about the difference between the two. And yes, the turbotech is nice as far as speed goes, but way to much vibration and noise for this shooter, plus at 70 lbs, it about pulls your arms out of their sockets if you shoot it a lot!
