I am new as well, and just bought a No Cam (picked it up today) as my first bow. I am 5'6, 155 lbs, athletic and can pull the 70# no problem. To me it feels about the same as 60-65# on other bows. For every day shooting I have it turned down to 63#, but when hunting will crank it back to 70. Yes, with practice back at 70 before heading out to hunt.
My friend came over and we shot for a while this evening, and he is about to trade his in on one of these after trying a few shots. Smooth and on point.
