You definitely wouldn't be going wrong with the Omega/Alpha setup. The Omega is a very versatile board, and the Alphas are excellent bindings for what you pay. Obviously, demoing is the best way to go to know for sure, but I think you'd be really happy with that setup. We've currently got all our 05 gear on clearance (but haven't changed our website prices), so email me if you have any more questions, or would like some prices.
