"one is none, two is one" is one of murpy's law.

i personally haven't had experianses with those kind of situations, but i have planned to use a vulcan sidepocket with sholders straps, as a pack which i will carry away from camp and for short trips. Haven't filled the sidepocket yet, since i haven't received the mainpack ( sabre 45 ) yet, should come this week. I want to find the ideal balanece of gear on the main and the sidepockets first before making a "kit" out of it.
