It's been a while, a long while, but I'll tell you what I remember.
I really enjoyed YAYOG. I have all his DVDs, even though some of the newer ones I haven't used at all or rarely.
His original YAYOG was doable for me. It was pretty short though and I like something longer. If I use them again, which I may, I would add on an episode of CS.
I really like his calm demeanor and his voice. His form is perfect. His YAYOG app was super inexpensive and great for travel.
At the time I was using his DVDs a lot I really liked them.
