I've always wanted to mimic a kind of Combat Sambo/Karate style (DOA may have been an influence). More like MMA fighting but I can kind of do whatever the hell I want and make it up on the fly.
Wanted to learn Combat Sambo a long time ago but lacked the strength and body mass to successfully pull off a lot of the grapples. Hell, I still lack the body mass for it but I do know a couple grapples that can deal a lot with easy body manipulation thanks to some Marine/Army buddies of mine.
Karate I was slightly interested in (one time kicked clean through one of those training boards equal to 3 wooden boards stacked on my first kick and really impressed the instructor during a school activity) but I dislike the "loud" aspect of it (I'm not fucking yelling every time I punch, I learned through farm work there are better ways of exuding the extra umph). In fights I used the Ein approach of "One Strike!". Fights have been few and quick. Get in the first punch and make it the last is how I roll.
