I am large, inflexible, but have good strength and reflexes. What martial art suits

[FeedMeAnswerst]

me? I've a little experience in Akido, but it was from personal defense training in a corrections officer academy. It did not really play to my strengths. When we went through multiple assailant drills, I found it easier to throw one opponent in the way of another than fight both at once. I have moved on to another career, but I enjoyed this training immensely. I am hoping to find another martial art I can take courses in for fun and to stay in shape. Preferably one that utilizes height and mass.
Er, I am not quite willing to commit to the kind of mass sumo wrestling requires.
