I'm using Zink right now thought about selling and buying the DSD ive heard alot of good things about them here on oldgobbler.
I hardly ever use decoys but i have DSD when I do.
DSD when I use one.
Same, DSD when I use them. That said, you're not going to kill any birds with the DSD's that you wouldn't have killed with the Zink's. I like the DSD's because I think they are more durable and they are made in the US, the turkeys won't care either way.
