OK, here's the situation.
You've got a close friend who has young kids. You and he live in a generally suburban area just outside a large urban area so you have access to lots of things within reasonable driving distance and both you and he make enough cash to live reasonably well.
The friend dops by or calls you one day about his 8 year old, and ask you, "I've been thinking about putting the kiddo in some kind of martial arts and I don't know diddly about any of that except for movies. What do you recommend I try?"
What do you say? One rule, since I'm going for style descriptions and recommendations for kids, so skip over the initial obvious response of "Just go around where you live and check out various dojos to see what interests the child" type of response. Or the other types of "personal good fit" responses. I already get that, that bit is common sense. Assume that everyone gets along with everyone and all the schools would be an equally positive experience.
But... recommending martial arts styles for children to begin with? That's my question.
