I think there is something you can take from everyone's kits out there. What to do and what not to do. The DR PSP is a great base for an EDC kit. (enough acronyms?)But I have expanded mine by including items and concepts I learned from my own background, reading books like 98.6* by Cody L, this website and others, talking to ultra runners and having a keen eye for balance between worthy item and replaceable item.
