Do you feel it would be overly big for a day hunt?No experience with eberlestock but the SJK bounty 2.0 is a great setup especially considering the price. Not as modular as a kifaru by any means but similar design as far as the meat shelf goes, the frame is definitely well built and rides very comfortably compared to some other budget packs I've tried. Had it loaded with over 120lbs this spring and was pleasantly surprised at how comfortable it was hauling that much weight. My only complaint is that the bag is a little bit small for 4+ day late season hunts when I need a few more layers in the pack but lots of attachment points for extra pockets, with one medium sized pocket and a 1000ci lid the pack is good for over a weeks worth of gear.
Get the nalgene holder while you're at it too, the tarantula bow hook is also the best $10 piece of gear you'll ever have if you're bowhunting and fits perfectly on the PALS webbing on the SJK hip beltOh, and whatever pack you go with, I highly highly recommend a Kifaru Gun Bearer. Most return on investment for a $30 piece of gear you will ever find.
