New Mystery Ranch Ultralight frame compared with every other most common Mystery Ranch frame 

Misnamed?

If you prioritize durability choose the Overload, it is 7.8lbs. If you value a more reasonable base weight (5lbs) and like better control over the feeling of your pack weight with the high up load lifters, go with the Terraframe 50. You can really feel how much stiffer the Overload frame is and you can also feel the increased weight. For 85% of my use cases the Guide light MT frame is excellent, but its really nice having an Overload knowing that I will not have to worry about long term buckle breakage or material breakdown with hard use. If you were in a sinario where you could no longer procure replacement parts or professional repairs, having a NICE frame pack is invaluable.

@@Two-Stack Thanks man, I really appreciate you taking the time to reply. I tried the Terraframe 50 in store and I really didnt like that i couldnt tilt my head back due to the tall load lifters. Packing it with 40lbs of weight I did feel it take a toll and would not enjoy lugging it through rough terrain (probably skill issue). I really do like the low base weight though. Despite the higher base weight, I also like the fact that overload is 500 cordura ( even though I wont probably abuse it that much) its good to know its bomb proof. I wish MR sold the overload sling separate from the frame. I think I would've instantly bought one by now. Do you notice a difference carrying 40lbs in the NICE frame vs Guide light MT?

Weights are all on the product pages, the Guide Light and Ultra Light frames can carry 150lbs, the Pop Up frames are rated for 80lbs. The NICE frame can carry over 200lbs.

The 3 Day Assault or the Pop-Up 30 would probably be the best options depending on whether or not you are wanting to use the Overload shelf feature.
