I'm 5'3, 125lbs, so I don't want a huge one. Right now I have a camelback mini mule (50oz). It is really nice becasue it is small and not bulky especially downhilling and freeriding. It has enough space for 2 tubes and tools. I want a pack for longer rides. It want a little more water capacity (probably 100oz). I want it to be able to hold my mini DV camera wrapped (to use w/ a helmet cam), tools, and a sandwhich. Basically twice as much water capacity and a little more room. What are some good ones? I like the Mule, I think that might be a good option for me.
