Hmmm... tough call.
I don't think the choreography is all that complex; IMO, it's about middle-of-the-road when compared to Cathe's other videos. It may *seem* more complex than it really is, though, because it's not broken down as in the older videos like MSB and Step Heat. Like Step Works, it's helpful to be familiar with Cathe's choreography, but I don't think the moves are nearly as complex as that or even Powermax.
Be forewarned, though... I don't usually have much trouble learning Cathe's choreography. I'd like to hear what some of the more choreographically-challenged Cathe fans have to say about this.
