Well,I took Ronin Goju,and loved it.The karate do goju ryu is probably very similar,it's probably an aggressive,mostly offensive style.It probably isn't to fancy,you wont be learning very decorative move's,but it's probably great for self-defence or kumite competiton's.I placed in a tournement with goju when i was like 12,now i'm 15,and a little wiser,so.... its probably a very straight forward,punch the opponent in the face style. good luck with whatever MA you chose and enjoy
