I train muay thai which has good clinch techniques great for trapping. British ju jitsu which is a mix of judo, ju jutsu, aikido, catch wrestling, boxing, karate and kung fu. The ju jutsu and judo element came over in he 1900's see bartitsu
http://www.bartitsu.org/. I worked door security for 6 years whilst going through university so the standing element of ju jutsu, muay thai and wrestling came in handy, and gave me good grounding for other worldly jiu jitsu styles. I enjoy Martial Arts keeps me fit and mobile just reading a book on Ashtanga Yoga looks pretty interesting something else to add to the pot.
