Anyone use long velcro straps or something else that offers a little more adjustability to get things tight but not so tight that it causes your sleeping bag looks like a tube of toothpast that got squeezed in the middle?
Having your sleeping bag look like "a tube of toothpaste that got squeezed in the middle" is far better than what your sleeping bag looks like after a car has run over it

That's what happens if the bag falls off because you don't have tight enough straps. Compressing the bag doesn't do it any harm since you already compress it to put it in a
stuff sack.
Personally, I'm more concerned about the hooks on conventional bungees and what they do to the bag and stuff sack. I use
ball bungees (4, one at each corner of the rack) because they are easier on the bags.
