I can judge and will if I see someone riding in a wire tie down or other such nonsense.
(And if you don't know, Brett Monroe was on the most recent cover of Barrel Horse News using a wire noseband tie down, winning the 2012 BFA World Championship Barrel Racing Futurity. Which is where this whole discussion is stemming from.)
You don't know his horse. You don't know if he usually runs in a leather tie down, but wanted something stronger "just in case" for competition. You don't know the horse ever cut themselves with the wire. You don't know the circumstances.
No, I don't agree that he uses one either. If I needed a tie down, I'd use a leather one. But I won't judge him. I am in no position to. I don't know the circumstances, and I am not anywhere near his caliber status. Clearly he knows what he's doing. He's been successful for decades, as have his horses.
