For the last few seasons I have been using a Kuiu venture 1800 and it worked great. Biggest deer I hauled out in one trip was 135ish pounds. The 2300 pack would handle a little bigger deer. If you are not going to be packing one over 2 miles, those 2 packs work fine but you will feel the load after a mile. Not bad uncomfortable, just not full frame easy. Using a kifaru duplex lite frame and stryker xl bag this year. Training sessions with 100# on the pack have shown this to be very good switch for me. This pack fits my body perfectly and that is a big key for hauling weight.
