Agree.
I prefer nylon straps or velcro straps. For short lengths I have also used toe clip straps.
If you are dead set on bunges - I use bunges to strap light weight stuff like a jacket or a cloth briefcase on the back of my motorcycle seat. I have pulled some of the bunge through the metal hook and put a slip knot in the bunge to shorten it. But I have never used a bunge to haul touring gear on my bike.
