I had them but sold them. I think if you are looking for old style tribal, they are good, but there is one major thing missing and this is a big flaw: the cues and transitions. Also the FC ones don't have many cues in there. So if you want to use these videos to dance with a troupe you'd have to make up your own.
I personally think it is a commercial trick that they didn't put it in there, because even if you have all the DVDs, you still would have to study with them (or make your own, but not everyone is good at that)
