Have had the pintler for the past three seasons. Haven't backpack hunted with it, but have hauled out several critters. I love most things about the pack. The tri-zip design allows you to open up the pack like a kitchen cupboard and actually find stuff rather than rummage blindly like you do with a top loading padding pack. If you've not had a pack with a load shelf, you're back and shoulders will thank you when hauling loads.
The one thing I don't particularly like is that the pack is quite 'strappy' - too many and too long to be super practical and require velcro strap keepers, which are a PITA. My approach has been to set the pack up so I don't have to do a lot of strap tinkering. Ultimately I may actually take a few inches off each one.
The pack is built tough and can take a beating. The belt and harness are plenty luxurious. Although it weighs more than some other name brand packs out there in this same class, the MR Pintler is a great choice that balances function, durability, and cost. I think you've made great choice and will love it!
