I do quite a lot of wild fowling on a big expanse of water, (22 miles long 1mile wide), tufted are one of the min species of ducks we shoot when the water gets over 6 feet deep, and can provide good sport. We set up in the dark for a morning flight, we always shoot more on a morning flight that an evening, put out decoys like you would pigeons, we use tufted and pochard decoys, but they will decoy to anything, as long as they have clear water in front of them when they land in case they need to take off, they can provide good sport. One thing I would say is if you do decoy them and one comes down which you think is winged, a double tap is in order, they are not as bad as pochard but buggers if your chasing them round in a boat trying to stop a cripple.
