I just aquired an Emerson Krambit , It is one awsome beast . It is fast and mean . I've already tagged myself with it twice , and nailed a pair of jeans . I've had some MBC training , obviously nowhere near enuff . As a result I've ordered a trainer and the videos . A close friend played with it , and even after being warned still tagged himself in the jeans . I think it would be good to have the trainer and the Krambit available as a boxed set . It would prolly save unco-ordinated old guys like me from trips to the ER .
