O.K. I'm going to go out on a limb here (is that what is known as a "pun"). I would say it has to do with the bow and its quality. Bows such as yours definitely DO NOT leave them strung. A lot of the rules have been passed down from the past generation of recurves (wait a minute that could be me!) I've shot the Bear recurves, as most of us have, as the only bows I've ever shot. They were all made in the 60's and I still have and shoot them occasionally. We just did not leave them strung and that was that. (I had a friend who had one of the first Allen compounds and even He unstrung (unscrewed) that.) I got into the compound bow craze, GASP!, for a few years, then found myself looking for a new recurve. By new I mean current mfg'ed and not custom made.This was 1988 and there really wasn't much out there that "I could find at the time". I stumbled upon Screamin' Eagle Archery in the very early 90's. I bought a Martin Hatfield T.D. recurve 65#@28". I might add it was a beautiful looking and shooting bow which I have used, a lot, until 3 years ago when I ordered a Fox longbow from Ron King in Oregon. Along with the bow I bought from Paul Brunner of S.E.A. was a video (VHS). To my astonishment, Paul said it was not detrimental to leave your bow strung, this particular one anyway, while not in use, as opposed to the recurves of the past. O.K., I went with it during the spring and summer practices, I would sometime leave it strung for long periods of time, I'm guessing here at say 3 months at a crack. Still I am from the old school of thinking and when I thought, "HEY this thing has been strung for a while", Id unstring it. AND, I never let it strung during the winter months or what I would refer to as storage. In the dozen or so years of use I can not detect any loss of poundage, of course I don't have any equipment to test it and I would have had to do a before test anyway,And I'm not going back in time. That bow is pulling the same now as it ever did, but then again I'm a dozen+ years older too. So, I would have to say, Unstring it, always. Better to be safe than to possibly ruin a nice bow. My longbow? I never asked what the effects might be to leave it strung. I,m not going to, it is ALWAYS unstrung when hung up for the night. CRASH87
