I found it exceptionally long winded and repetitive. I swear I read at least a thousand paragraphs until he got to the crux of the issue, being the middle finger fulcrum. That said, that's my only gripe and I do agree with his ultimate point.....although, I wish I'd read the shortened version, Bruce
Personally I've always found both more control and more leverage over the stick using predominantly a thumb and middle finger fulcrum. My fore finger doesn't "point forward" per se, but it does rest gently on the side of the stick when playing German grip. That's not to say it lies there dormant, forever amen though. It certainly comes into play to aid control from time to time.
