Elkcrazy8, If this is a RMEF shindig you can have no more than 4" bell on your grunt tube and no more than 30" in length. It is broken down in to two calling sets 1 min. for cow/calf and 1 min for bulls. I would take at least two external cow calls and a squeeze call. For bulls Volume is important. Can you buzz bugle? It is a must. Panting & glunks important. Any elk sound you can make. The bigger and bader the better. The judges aren't looking so much for reed control, multi pitch stuff, that is what I am really good at, but it doesn't score well with a lot of the judges.
Go To www.rmef.org/convention/2005/images/rules_05.pdf This will give you rules. Ask any question you can think of, pick my brain, I will help you any way I can. No I can be there[:@].
