I did Judo and TKD as a kid/teenager.
In the last year I started doing kickboxing, moved cities and am now doing Muay Thai at a well known MMA school here in town.
I'd say the school itself is probably more important than the Martial Art. I'm not looking to go pro, but I would like to be able to compete, so it was important for me to find somewhere that has experience turning out pro fighters so they know what to do.
