I have the same question as CircleC.
I've heard good things about Coates and have ridden a Leddys before. But my current cutter is an Older Simco. It's the only one that I have ever been able to find a pocket in, and that includes several reiners, ropers, and barrel saddles.
Please excuse the horse it's on, if I had my way about it he would be culled in a hurry (he is PSYCHOTIC).
