Thanks guys! Yeah awhile ago I had her in a pelham because she would NOT stop yanking the reins out of my hand and dragging me around the ring. It was a temporary tool to get her under control while we worked out our training issues. Once she got over that and started carrying herself, we went back to a single jointed snaffle and that's what I've had in her mouth since then.
Regarding the roller, she is always licking and kind of chomping on her current bit. But would adding the roller only encourage her to do that more? Because I don't want her chomping, she gets so distracted when she gets into that habit!
