Thanks for the replys Guys. I was mainly wondering if sometimes lasting only one jump was normal or I'm just not good at double wrapping.
In my original first post I wassn't suspecting the rubber bands as the issue, but mentioned the bungee style elastics that I had been using and had since had hard openings, and then switched to rubber bands double wrapped. I have had no hard openeings since using the rubber bands double wrapped but replace them evey jump day, sometimes a couple times a day :)
