O.K. You guys sold me. I am putting TNS on my Christmas list. Just one more question. For those who have Kristen Kagen's STW2 too, is the choreography similar, more or less complex? It took me quite awhile to pick up the choreography on that one, and I'm not as fond of STW2 as I thought I would be. Maybe it's her personality. It is a sweaty workout though. So any more thoughts on this? And, I will leave this die now. Thanks!
