I used the LLBean carryall this year with a couple dry bags. I think they were 20L's.
Pack weight was about 40#'s. No elk, so no heavy loads. It carried the 40 some pounds well, but the pack is a bit small for me. I ain't 5' 8".
The straps also slip pretty easily. I was constantly tightening chit up.
It's cheap, decent suspension, and you can do a lot with it.
I'm going to pick up a used Arcteryx Bora for next season. Loads of really good, slightly used, packs out here for under $200.
