I occasionally ruck with anywhere between 20-50 lbs.
Right now I am using Mystery Ranch NICE frame with Go Ruck Rucker strapped to it. However, despite the adjustments to the torso length, and tightly synching the hip belt, the rear of the frame still ends up lower than the front of the hip belt.
As such I am looking for suggestions for packs that hold about 3000 cubic inches and 50-80lb max. Can be either external or internal frame.
I also used Camelbak Trizip which I find a bit more comfortable than MR NICE.
