RE: 60lb pull good or go bigger?
Well seeing that many, many traditional guys are shooting animals all the time with their setups, 60lbs will work just fine on your compound. Your only drawback is that your shooting distances will be less than if you were pulling 65-70.
You can always set the bow up at 60, shoot that for a few months to get your "bow" shooting muscles strengthened up and then dial her up a bit. No reason why you can't work up to 65-70lbs by next hunting season with ease. If that's where you'd like to be at.
