Scoter,
I've got a Bison Gear Selway made out of filson wool that I use for whitetails in Michigan. It is heavier than some of the other packs out right now, but it's really put together nicely. It is queit, and has enough room for me to pack in my cold weather gear for a long stand. I used it on my elk hunt this fall, and that took some getting used to. But now that I've learned to use it, I like it.
By the way, Bison Gear is usually at the Kalamozoo expo so you could see their stuff first hand.
Good hunting,
Bret
