I can see the desire for a smaller pack for side country and even close in back country. Riding with a pack sucks plain and simple, so the smaller the pack the more fun it is riding. I keep my pack as small and light as I possibly can. Carry a small stove to melt snow for water instead of carrying a big ass water bladder, keep my essentials as small and light as humanly possible.
My thoughts exactly. Plus, you gotta remember killclimbz, you're a pretty big dude. A 30L pack probably feels quite a bit smaller to you than it does to me.
