I'm not arguing the quality of Roy Deans videos... but you didn't read the OP properly, didn't pay attention to the forum this thread is in, the section of the forum this area is in, the subsequent posts by the OP that clarified a few things, and as a result gave a suggestion that has absolutely no relevance. That's not helping, that's ignoring the actual thread and request itself, and arrogantly thinking that your form of training is going to be relevant when it's simply not.
Look, you can 'dislike' all my posts you want... but you have yet to be able to actually argue against them. And I'm not running anyone off anywhere... for the record, I know of some two dozen or so "Bushido Jujitsu" groups... all different, but all modern, Western interpretations of what they think "jujutsu" is... none of them are legitimately traditional (in the sense of traditional jujutsu), with quite a few being less than spectacular, but with some being quite good modern systems. Until we know which one, we can't say anything definitive... other than that it is not something universal enough to actually have the material and resources out there that the OP is after, and that it certainly isn't traditional jujutsu nor BJJ.
I heartily recommend you get that chip off your shoulder where I'm concerned, take a step back, and actually read what's written.
