Huge fan here too, loved the cardio and the HIIT, but burned myself out by following the rotations for 10 weeks. I should have rotated in the advanced dvds sooner to add more variety.
I only did the Fire 60 from the advanced, I really really liked it, even near the end of my run with TF, I popped in Fire 60 and thought it was great, I might even do that one tonight come to think of it.
I did not like the sculpt or tone at all, I really don't like all that band work, I find it tedious and boring. So the upper/lower body in the advanced were a waste for me, and the 10 minute abs, well so many other dvds could replace that.
I never got around to doing the HIIT 30, I will use it though, just need a break from it.
So overall, for me the advanced workouts were not necessary. I'm not too upset over the purchase, but that's a lot of money to spend for 2 workouts.
