When your young your better off sparring, but I'm thinking two man forms could be usefull when you get past the competing/hard sparring days. In Robert Smith's "Martial Musings" book he talks about old judo masters doing light groundwork to keep their fighting skills somewhat fit...I'm thinking blend light judo/bjj with maybe some light push hands and some non acrobatic two man gung fu sets, you'd be good to go...

I don't do two man sets, but I'm saying I think it could be usefull when you become older...What you think?
