Micheal Arnette said a mouth full.
My Predator weighs in at 73lbs at my draw length, but feels smoother to draw than many others I have tried at weights much less.
Even if you can handle heavier weights, sometimes your draw length begins to shorten as you compress your skeletal structure. I personally believe you are much better off with a bit more draw length than a bit of extra weight.
For me, much beyond seventy pounds, I find my draw length beginning to shrink.
Again, what Arnette said about high end, versus low end, is good advice...IMHO.
