His material is top notch as is John I do not provide testimonials to many people and I get asked a lot - I gave John one without him askinh
I do not know John so i might be totally off here, but i assume his practical knowledge doesnt come from countless street fights and that sure as h... is positive. It is a testimony off the fact that you can build up a solid practical foundation for self defence from using your head(not to block), investing in the right kind of gear, dropping down on your ego and test, test, test and test. If this is indeed the case with John, as i think it is, it provides a nice balance to all the street brawlers claiming the only way to gain a real understanding of violence is to engage in it. Some of these folks are bearable to spend time with but the vast majority are not.
