Are you sure about this advice Mr. Pollak? Does Dr. Dave confirm your contention that the rail must be hit first when the object ball is frozen?

Apparently Dr. Dave does have video of this - start at 128 and go through to 141. Looks like the shot can be made by hitting the rail first OR the ball first.
John, I don't like going to other sights.
