don't use a blind but i have the Flambeu purrfect pair, they work good.
I've had 2 Jakes and a hen run up perfectly from 60+ yards, i missed.
another time i had a Big Gobbler run in from 30 yards to 10 yards got side tracked from the decoys from me moving around (getting the single shot hammer back and adrenaline) it looked at me and side steped to the decoys....smoked him!
the rest of my turkeys i ran into (before getting setup and i called in)
