ok so on D-Rings:
why is that preferable to say a cam buckle (timbuk2 style) other than the difference between metal and plastic? Is it possible to get a metal cam buckle? for the record, i am calling it a cam buckle because thats what it is called in the website posted in this thread. I have no idea if thats a brand name or what.
how easy is it to adjust while on the move?
