Onmis have been out for awhile, TenPoint puts stickers on their bows stating to use them. Won't suffer any major catastrophe if you don't use them. Any "bow tech" that deals with crossbows that pays even a little attention to what's going on should no about them. Technology is moving quick with crossbows, good techs need to know whats going on. Run, run as fast as you can fom that shop.
