Having hunted over both last year, I will stick with DSD 110%
The DSD can withstand mounting, pecking, beating, etc. I like how the ACE is firm, yet somewhat pliable.
The Zink looks fine, but almost impossible to keep standing if mounted, pushed around, etc.
Size is not critical to me, I've killed maybe 40+ birds over the tiny Sceery inflatables.
I think the Zink is a bit rich at $80. For $40 more, I prefer the DSD.
I do think traveling with either one is cumbersome, so I use other decoys, or no decoys when traveling for the most part....
