Rost, I agree with you or that the G1, G2 frame did not fit me well! I now have the new , I guess G3 and it is a whole new animal.
The internal frames are where I would suggest you try. I had the Just One and it is like a drunk hooker on your back with any more than 50-lbs.
If you can try one of the internals is my $.02. Not trying to hype them, I just spent way too much trying all the other makes.
Late Season is an awesome do all pack or a T2.
