I found this two part video, I have no idea of the accuracy of what it shows. Since I don't have the ADT info to come pair it to. So take it for what it's worth.

It was shot by a bowler having his grip fit.

Thanks for posting this. 

Was it removed from BBE?

The post is still there, just removed the links to please menorevs because he says "This is part of package you receive when you buy the product."

I doubt that video is part of the package or even showing exactly every step in how its done.

And its unlikely that bowlers video is violating slowinskis copyright or what ever.
