I have a half dozen fully flocked mallards and a half dozen GWT. I only use them occasionally and have shot plenty of ducks over them. Typically I just use them when wanting an ultra realistic small spread. On the other hand I use regular painted decoys 90% of the time and obviously shoot ducks over them in all conditions.

What are your thoughts? Do they make a difference?

I cant really say they they make an difference but for some reason am wanting to pick up a half dozen fully flocked wood ducks.

I hunt with regular painted woodies, usually 4-6 with a couple of teal or gadwall decoys 10-20 yards the other side.

I quail hunt with a bunch that have bought every single item that Bass Pro shop and Cabela's sell -- that has anything to do with quail .------------ I call it their mardi gras costume. Same idea with decoys, it is fun to play with, but has nothing to do with decoying wild ducks.

I think they do on geese but not ducks

Most goose hunters use white rags for decoys .
