What kind of straps does everyone use? I have seen people use straps with a carabiner attached to the end so that the hook doesn't fall off while towing, which makes perfect sense but I was wondering what people think of the cam buckle style over the ratchet style. I'm sure that the cam buckle ones are fine and I bet that they are quicker to do up, but are they safe? They seem a bit risky to me. Let me know what you do and what works for you. Thanks, Paul.
