Kimura Trap System - one year later, Efficacy?

So last year the Kimura Trap System DVD was the big thing. The whole concept of using the kimura to defeat guys, like wrestlers, with tremendous top game. It was a big deal to get your hands on that DVD.

So a about a year later, now that people actually have had a chance to master the techniques, have people been able to rate their effectiveness? They seem like an innovative way to work of a basic move, the kimura, to effective ways to get off your back or attack in ways they might not see coming.

What are everybody's longitudinal reactions?
