Wrist-rocket, Marksman or Trumark, these are simply terrible slingshots. The wrist brace blocks all possibility of learning the lightening fast 'intuitive shooting' skills we all aspire to. Equally important, all tubes (like those used in Trumark designs) have a high drawing weight but really low power output for the effort. Fine if you want to pretend you really could hit something over 10 feet away, but... in 2012, Bands rule (and have for a long time, actually). Check out simple-shot.com. Or search 'slingshot' on YouTube... there's a big world of slingshots out there, and traditional designs really have proven better. And way nicer looking, too!
