I' ve heard this topic batted around on numerous bulletin boards and it seems like it' s usually split 50/50 on whether to unstring or not after each use. For me, when I' m shooting a lot, I usually just leave my bow strung and have never had any problems. If I don' t believe I' ll be shooting for a few days, I' ll unstring it. Someone made what I thought was a good point to me and that was wouldn' t the odds be higher you' d damage the limbs by unstringing rather then just leaving the bow strung. I' d say to be safe, ask the bowyer of the bow in question and follow his advice.
