I would suggest trading the Straight Meat Mallard in for his new Dead Meat Mallard, I think that call is alot "duckier" than the SMM.
I would also suggest ordering the calls strait from their shop rather than going to a local Cabelas or mail ordering from Cabels and only having limited colors to pick from. If you order from their shop you'll get whatever color YOU decied, not the best of what Cabelas offers.
