As I said, I don't think it matters if you're all that and a bag of chips in another style (and your skills are current), or you aren't. The reasons for leaving it outside are different in the two cases, but the result is the same.
Completley understand. I'd rather do Aikido any way. I have no wish to harm anyone, was curious if it was application to use in case I couldn't use aikido. I am only 6th kyu (first belt test). So I probably don't have enough aikido experience to defend myself if I had to as a last resort.
