So I just got back from a two week festival in PA where I spun, taught, and hung out with a bunch of phenomenal bellydancers from all over the US. We started to talk about the prevalence of poi in the bellydance world, and whether anybody had truly fused high level bellydancing/"world fusion dancing" and high level poi. None of us had seen it - we surmised that while you can do both, it is impossible to devote the amount of practice seen amongst the world's best bellydancers and the world's best spinners, to both disciplines. Moreover, complicated spinning patterns take a lot of concentration, which would be very hard to combine with the kind of muscle isolation required for really good bellydancing.
Most videos of poi spinning bellydancers involve some basic dance movements, and a great deal of spinning. Sometimes, you see a little more bellydance, but with even more basic moves. At it's best, it's like the dancer/spinner was trying to do both at the same time, but never as a fused art.

While having serious dance skills helps with body awareness, posture, and general body movement, are there any videos out there of super skilled bellydancers who spin really well?

[In case anybody was wondering, I KNOW that it's not all about skill, and both bellydancing and spinning are primarily about having fun. I'm just looking for an example of high level proficiency in bellydancing poi]
