I am in the process of build my BOB. Right now I am using a cheap backpack with a hydration system. I am wondering which pack would be better. A dedicated hiking/camping pack or a more "Tacticool" pack like some thing from Blackhawk or Maxpedition. I kinda like the later of the two because of the ability to tailor it to your needs with different pouches and other MOLLE type products. However, the hiking packs have nice support frams, waist belts, and better padding. I guess what I am asking is what types do you guys use and why did you choose them? Thanks.
