Dakota are nice, but IMO they don't rate the premium price.
That's been my experience. I have a half dozen fully flocked mallards. They look good, but I don't necessarily think they were worth the extra money. Next time around I think I'd look at Avian X.
I have the Avian X as my good set and the Tanglefree's for beaters. I can't say I have seen any difference between them, hell not even my buddies 6 dozen DropZones that are amazingly accurate seem to work any better.
