I agree Frank. I' ve seen the new mathews/ Jeff Murray blurb. Funny, when I hunted with Jeff he was more a speed freak then he seems to be now with his 27" draw (he was toting a conquest and a Z max then), but that was in ' 97 before speeds took a big jump. Perhaps fps, energy and trajectories are where he wants them now so he' s looking for smoothness, I don' t know.
I chose Darton as their CPS cam on some of their bows state 312 fps IBO, very close to the 318 fps of my Hornet. I' ve never drawn one, but every post I' ve ever read speaks of the Darton' s silky smooth easy drawing characteristics and ability to actually deliver stated specs. Since it is close out of the box apples for apples, I figured it would be a good one to hypothesize with in order to avoid the " don' t gain much from 80# due to the FDC over 70#" you alluded to above, which I whole heartedly agree with.
I know what drawing a 70# Hornet (Bowtech PF cam) versus a 70# MQ-32, FX and Q2, the mathews seem much easier/smoother to draw, but were much much slower than what I was looking for (Hornet vs. MQ 32 with identical set ups, hornet 50 fps faster). I assume the Darton at 70# would be just as smooth if not much more so than mathews, but store more energy comparable to the Hornet.
I did note on Darton' s website they only state bows up to 70#s, so I don' t even know if an 80#er is possible, but it' s fun for discussion
