There's actually a bunch of good info in this thread http://www.bowlingboards.com/threads...4563#post94563
And also in this article. http://www.modern-bowling.com/Bowlin...-Vegas-NV.html

I'm not very good and just recently started throwing a hook but the article is well written and has a bunch of good info.
