I tend to lean towards the more brutal systems of Haganah, Kapap, Lotar, and Krav Maga. Oh, and Gunslinging of course; I'd much rather just shoot someone than risk getting into a game of fisticuffs with them. It's safer that way.
I like it; it's simple, quick, and devastatingly effective; leaves nothing to chance. In my opinion, if one must fight, they shouldn't fight fair; they should fight dirty and make sure the other guy doesn't get back up. Fighting is ugly; I hate fighting, but if you must fight, WIN.
Will I learn any other forms? No; I have not the time, the money, nor the inclination to learn any other systems. Most other systems take too many years to learn, and are composed of fancy moves that become irrelevant when your gross motor skills fly out the window upon the engagement of your Fight or Flight response to a real-world violent encounter; they are sports and games that are best saved for the dojo in a controlled setting with padding and rules and regulations, or in an arena with spectators as a social sport. I prefer tactics that have been battle-tested by military personnel overseas.
