In my opinion, it's not worth it.. No keels and heavy. Sorry, but I can't believe ducks like cork better. Even the late season birds come into them......ok ......I'll believe it when I see it. G&H and GHG have much more detail, and are more durable. I can understand making a few as an offseason project, but having an entire spread....I'll have to pass. I have made and used a few cork bluebills in the past, but they still didn't come close to my G&H. Not to mention them cork dekes are freakin EXPENSIVE$$$$$$.
