The Elbow on a Shelf concept was a tremendous help to me for smooth longer distance casting. That along with the minimizing wrist motion are very important.
It is not the conventional style of casting with most FF that use the 10:00 to 1:00 rotation method. This style works fine however, it requires very good timing and more hand / wrist strength than the Lefty Kreh style.
Lefty's basic principles of casting sound strange at first reading, the longer I study casting the more I appreciate how they are universal to any style.
