Thanks, Nodog. You're very fortunate. I'm not in bad shape, either; just not conditioned, obviously, for this type of body mechanics. Any helpful advise? Say, an exercize routine that'll properly build my shoulders for this particular activity? I'd imagined good old-fashioned push-ups should help seeing that the mechanics aren't dissimilar. When I've healed a couple days, I'll try that. In the meantime...
