Sup. I'm looking for the best martial arts where self-defense and survival in "any" situation is concerned, preferable can be efficiently lethal and non-lethal at discretion and with many practical day to day uses (For example, with wrestling your form and finesse when grabbing and holding doors and stuff changes.) I read elsewhere that apart from knife fighting and guns that Krav Maga, Spetznaz Systema, BJJ, Pankration, Muay Thai, Wing Chun and Sambo are the best and most practical for this. What are your thoughts? I currently do Wrestling and like MMA.
