This is no way a replacement for the diamond system or learning your angles but here is something that helped me with my banks in tournaments when I first started. The layout of most pool halls are pretty much the same rows of tables about one table width apart from each other. If while on the bank you look at the table next to yours and aim for the pocket on that table you want to hit It should come close. If it misses adjust your focal point on the other table until it hits the pocket you want and use that point. I hope this helps someone if not I am sorry.
