Exo 5500...phenomenal pack. I just packed out over 1/2 a cow elk yesterday in one haul with mine...Steep nasty downfall country, and the pack handled everything great...I weighed the pack at just over 110 after i got home.. I used it all fall as both a daypack and a multi-day pack, and it just works great no matter! I know mystery ranch makes good packs, but they tend to be on the heavier side, and ever since i wore a buddies Exo I couldnt believe how comfortable it was for me, so i ordered mine the next day this spring. After 8 years of guiding im pretty darn particular to the pack I want..I have had most all the major name brands and always find things i dont like about a pack whether it be minor or major...I have yet to find that in my Exo. The frame bends when needed if pulling your bow, but is rigid and solid when it comes to hauling the heavy loads. I think you would be happy either route, but my vote is for the Exo, as I will not be buying another pack for many years to come
