I've done Bob's basic twice and his advanced at least once (I think twice). I've also done Appleseed once. I agree with Tack in that I would recommend doing both if you can. However, if it were me, I would put Bob's class as a higher priority than Appleseed. Appleseed is great history and a lot of really useful drills to bring your groups together. But Bob's classes are much more aligned to what I think we will be seeing in October.

But I'm willing to concede that YMMV.
