I have more than 40 mini/double hooping tutorials on my website. All free.
They posted the intro on YouTube. It's a little cheesy. :)
The DVD is good if you're a complete minis beginner. It literally begins with: this is how you spin a mini on your hand. Some of the techniques and tips are really helpful. I found the practice drills helpful. I got it because I'm just kind of into having a library of hoop DVDs as a resource and haven't worked with minis much. (I have all of Hoopnoticas DVDs, Hoop Technique and Home of Poi's beginner poi DVD is on the way, plus I've got Betty Hoops' DVD too... I should get HoopGirl's...). It's got some cool basic tricks in it though.
