A friend of mine allegedly trained in Krav Maga but he's overseas right now. I guess it's combat self defense. 1990s MMA-Bas Rutten! Where'd you find him! Amazing...his knees, elbows, chokes, ground and pound and joint holds are scary. I googled him tonight as I do not remember him.
I remember Royce Gracie [Brazilian Ju Jitsu-BJJ] from the early MMA days.
If I was 15 again I'd become a professional MMA fighter. At the end of my training [when I was older] I found out about & joined Ju Jitsu for a short time. But over the years I kept stopping my training when life events interupted.
If only I was younger. The 44 has stopping power. I'd recommend you practice if someone gets inside your guard [past your 44.] Some use a short hand held kubotan-it can fit on a keychain.
I'm not an expert and still learning. You are right about the Bear pepper spray. I think it's 10% pepper spray while most retail pepper spray is 5%? I bought several 10% in the past and gave one to my then girlfriend [my best friend today.] Hey at least you know your stuff. Best wishes.
