Since the title is "Best Speck Decoys, Opinions Wanted," I'll opine that GHGs are far from the best. My experience with both painted and flocked speck GHG FBs' durability has been "mixed" at best, and my GHG speck floaters flat sucked.
For my money, DSD makes the current best FBs, and G&H makes the current best floaters. (The most durable speck FBs were Hardcore's original '03 models, and the best body postured FBs were Hardcore's '04 and '05s, with the later two's great postures suffering from paint problems.)
If you think I'm wrong, you might be right.
