RE: goose dekes. which one?
IMHO it depends on you pocketbook and application. Cork is #1 but weight is a serious consideration. If one can get away with a dozen or under cork is the way to go. My second choice are Herter's. No plastics ride or look as good in the water as either of those two choices.
I've found over the years it's the simplicity in paint schemes that are the best for drawing birds. That used with proper decoy placement is the the real key year in & out for successful hunts.
