Most of the dvd s are extremely basic. I would just go on youtube. though I teach at hooping university... but I am here in Italy doing a Guinness record for Lo Show Dei Rekords and I am available to teach, live and in person. I am in Rome.
Safires tutorials have my vote too. I tried hoopgirl evolution but actually I found it a bit boring, lots of moves but not many that look really good or are very challenging. If I could go back in time I wouldn't have bought it, would have just gone straight to learning from Safires tuts. Good luck!
Wish I had the $ for a visit to Italy and a hoop lesson with you ;)
I think Safire's tutorials are really amazing!!!
I'm not sure how advanced you are, but the Hoop Technique DVD has loads of awesome stuff on it. Outside of that, everyone seems to agree that SaFire's classes are pretty awesome. Good luck!
