in youn wha ryu we are tought as tae kwon do students, my instructor introduced randori to the class about a year ago and as we progress we learn about aikido, hapkido, judo, chinese boxing and a few others, i'm ot there yet lol. the point is our style trains you to perform your martial arts, and also have a ready arsenal for a time you might actually need to use it. we have been critisized by the ussual "its not a rel ma" people til they come to a tourny. i think kerate will take you a long way but keep your mind open to the ground arts. you wouldn't want to have to rely on kicks and punches from on your back with a bigger person beating you up.
