Do yourself a favor and figure out some way to get it video, u may feel one thing and doing another. It's much rarer to have the shanks from the inside and the solutions are completely different than if you are coming OTT. ED Z suggestion about the swing against the wall is excellent regardless of which type you have, it's more of gettign you to better in swing fundamentals instead of a 'cure' for shanks...
