Go into the filipino martial arts. You will learn Panatukan, empty hand, and Dumog, wrestiling, both from a very free form methodology, and most important for self-defense, weapons training of the best kind. If self-defence is your goal, the weapon based filipino arts will make a lot of sense for you. I don't know how old you are, but if you are an adult, most life changing, or life ending encounters will involve being attacked by someone with a weapon, or a group of unarmed attackers. The focus on weapons training improves your empty hand applications incredibly. Once you train with the stick, sword or knife of the filipine traditions, which you will do from your first class, anyone punching or kicking at you will be at a disadvantage. the weapons drills increase your ability to see strikes coming in, because weapons are a great deal faster than the fastest empty hand techniques. The weapons training increases your timing because they give the opponent an advantage, so when someone comes at you without a weapon, it will seem like it takes forever for them to complete the action. A lot of empty hand arts do not deal as effectively with weapons as the fillipino arts do. I have years of experience in Kenpo,and have dabled in a lot of the other arts, judo, aikido, shotokan, sport karate, hapkido, iaido, western fencing and some others. I have yet to find any that are as familiar with weapons, that are the most commonly encountered in the real world. Just my humble opinion and my humble suggestions.
