It should real interesting next year for duck decoys, as Big Foot will be coming out with their duck decoys. If they are anything like their FBs goose, or Goose floaters, they will be simply awsome.
Personally I like the G&H shells, very durable and compact too. FBs are nice, but bulky too.
Also at times you can be a double winner, as many use Goose decoys and duck decoys in conjunction, so oppurtunities for both in the field.
