Necessity is the mother of invention! I always feared damaging the zipper,as well. I tied a short lead of nylon cord to mine and rolled my body, trying as best I could to keep the pull straight. Always felt rediculous doing it. Glad I'm not the only one now. I think there may be some very slight advantages to the back zipper. It's shorter and out of the risk of damage.
