I highly recommend Elknuts videos/CDs. They are not just hunting videos with a little calling lesson thrown in. They are: what are the elk saying to me/each other and what is the proper way to respond. They made sense to me and have helped me tremendously. He also has a "elk playbook" out this year. Have not seen it, but it should be helpful as well.
