I used flat webbing that goes from the rear D ring on the right all the way around to the rear D ring on the left. There is a girth hitch at the Front center D ring. On the rear D rings I put a Stainless threaded link (kind of a small locking carabiner) and on that I put a cam buckle. I tighten and loosen as need to keep the webbing flat but loose enough to grap on when needed. (That still doesn't solve (and may exaserbate) the problem of large loops in a folding situation.)
