Just in case it's of interest to anyone, here's an update.
After 5 days of shooting a couple of hundred a day, one of the cuffed tubes finally gave up the ghost.
One of my concerns with this method was that the cuff at the fork end might hide damage and that is indeed what happened.
It wasn't a dramatic failure. When I set up a shot, I do a full pull away from my aiming position just to be safe. The failure happened then, which makes me feel a little smarter than I usually do. Still though, safety glasses are our friends. The cuff itself is totally undamaged.
I don't have hard data, but I'm sure that this extended the life of the tube and it certainly makes tying them on easier.
I'm going to keep using the method for the time being, one to see if it actually does improve the life of the tube and two to see if I can figure out a way to prevent the cuff from hiding the damage. I'm also going to mess with different attachment materials and tension.
The damage is caused by the wrapping cutting into the tube over time.
There's got to be a way to spread that pressure out.
I would appreciate any ideas or advice.
The cuffed pouch attachments are rock solid however. I've been using them on bands too. So far so good.
