Opinions about the these tapes?

I just wonder if anyone have seen the following tapes. Maybe someone could give a little review.

1. Lucky 13 from Tony C.
2. Yoga for martial arts (from grapplearts.com)
3. Marc Eccards DVDs about conditioning for BJJ

I own the LUCKY 13 video. It's a kick ass program if you can get thru it, my impression is that most(including me) can't. I would suggest getting the LUCKY 13 primer CD first, work on it then move up to the video if you so choose. It's about 30min and isn't nearly as brutal but still kicks my ass.
