The best martial arts feedback, that you can surivive from, comes from sparring in UFC-style MMA format, in a dojo with considerate bushido and, even better, in competition, if you're fit enough. MMA involves more spirit, depth of skill, and strength then at least one Kendo person in our Forums suggested this month. That's what I like about Kendo -- frequent feedback, kind of like MMA, tho' a bit lighter on sharing pain. Kindly comment, please....
