RE: New to bowhunting and need...
I started with a 70# bow set at 58#'s. I QUICKLY went to 62, then 64 lbs. My new bow is set at 71#'s.....and I don't have any issues with it.
If you're brand new to pulling a bow.....I can see how 70#'s is intimidating. After building the muscles needed to actually draw a bow.....you'll see that it gets much easier.
I'd get the 70#.....and know that I had room to wiggle.
