Have any of you ever used sumo training to augment your aikido training? I was watching the most recent basho on banzuki.com today and suddenly realized that sumo would be a good way to learn to feel the energy of an opponent and counter before or as soon as the attack begins. Even as a kid I never thought of sumo as "a couple of fat guys pushing each other around." Now that I'm older and have some MA experience I realize even more that there is a great deal of skill involved in sumo and also that the "feel" of energy gotten in sumo might help me with my aikido.
