Burton's old tapes?

[Cj Lee]

I was flipping through some old mags and saw Burton Richardson's tapes (Unique). I have some of the tapes from his Defining JKD series and liked them. Does anyone know what's on tape # 6 in that series? From the promo, it sounds like there are drill for sparring. Just wonder whether anyone here has seen this particular tape and if so- pls give a short review.

Thanks!
