I'd say your 8 arrow buddy needs to spend less time on stand and more time at the range.[8D] As someone said, which ever you choose will work just fine on those little Hill Country deer. I'd shoot which one flies the best. Beg, borrow or buy a couple of each and see how they fly. If your set up is good they'll all fly OK, but I bet one will just have that extra bit of tightness to it's group. Heck, with that set up you'd be more than happy with a good mechanical and end all minor flight problems.
