I am looking picking up a new pack that will be pulling serious multipurpose duties. For the most part I will using either pack in daypack for but want the ability to expand the pack to haul out boned out deer. I do some scouting for high buck hunting (1-3) and then will be doing a four day 3 night high buck hunt. Things I like about the eberlestock is the built in scabbord, expandable when needed, price. I have been able to try one out with 55 lbs in it and it felt ok. The other thing I like is the ability to take out the superspike duffel and zip it on to the pack and use the big pocket to put meat in so that I can come out with meat and equipment in one trip. The mystry ranch I have heard carry weigh much better but am unable to get hands on one. I think with the load cells and daypack lid may be able to take out all equipment and bonned out meat in one trip but am unsure. The other thing is I have to have a scabbord for the rifle,I think I could pick up an eberlestock side scabbord and attach it to the mystry ranch with no trouble though (?). By the time both are equipt fully either with spike duffel or the other with scabbord/load cell, etc they will weigh about the same. Im hoping for feedback on both thank you. Other equipment is Looking at getting a tarptent rainshadow 2 #1 choice or the tarptent scarp 2, jetboil cooking system, not sure on bag yet something 15-20 degree temp rating.
