I received Rapid Fire 1 (POW) in a trade recently and just did it this morning. I really enjoyed it! I thought it was a great intermediate workout; I also think it will feel more advanced when I'm more familiar and possibly by adding weighted gloves (the pair I have stinks, so I hate wearing them). The only thing I didn't love was the set and the fact that you couldn't see the modifier, but I see that in the two later releases, Susan seems to have addressed both these issues.
Anyway, the workout was a LOT of fun, and I really enjoyed her combos. I love when instructors do stuff that feels fresh and new. I know some people have stated how much they love her kicking, but I thought the boxing was awesome! I'm a much better puncher than kicker, but I'm willing to be assimilated.
So, I was looking at her other two workouts; how do these compare, intensity-wise and for fun factor, with the first one? Are they chaptered as fantastically? Do they have as many premixes? How does the weight/KB/other work compare?
