Okay so I have a QH mare I've been running in rodeos 2-3x's a month and I need to upgrade a bit I think. She is a free and strong runner who rates and lifts on her own , all I have to do at a barrel is check her. I have been riding her in a 3 piece jr cow horse with a copper roller in the middle. I broke her in a snaffle. Now we have been hustling through the pattern and she is still light as ever while running I just have to check more at my first barrel. I had her in a sliding gag twisted short shank combo but she HATED it. We would run past the first barrel from her shaking her head and bucking , I think it was hurting her. She has her feet, teeth, saddle fitting and chiropractor checks regularly so pain is ruled out. So I have Absoleutely no whoa In my bit . So I need a light bit but with more whoa. I was looking at the 3 piece sweet 6. Opinions? I have a video if needed.
