I've been shooting Black Widow MAIIs for almost twenty years, without so much as a single issue. In a literal sense, they are works of art, but more importantly, they are tough, fast and accurate performers. I shoot weekly, year round(some would say weakly, year round) and just leave my bows strung and hanging on the wall for display and convenience. A couple of my bows have been strung for close to fifteen years!
Can't go wrong with a Widow. Many vintage Widows in good or better shape often sell for close to what they sold for new.
