I don't understand why you are challenging us on this? Neither of us suggested it was possible.My challenge is the same to YOU Dave! Just make the last shot in my video with OUTSIDE English! For $5,000! I will give YOU a reasonable amount of tries! Or, I will shoot it with YOU or BOB, shot for shot for $5,000! First one to make it, takes down the CASH!Many supporting videos and additional info (illustrations, articles, explanations) on this topic are available here:
rail cut shot resource page

Inside (running) is definitely the right play here, either ball first or cushion first. This technique is covered in detail on my resource page.

Dave
