I work at a rescue as an apprentice trainer. I love the constructive criticism. Gotta learn somewhere right?
Well one of our volunteers is constantly nagging at me about using a bit. The first horse I trained which I ride a lot, bareback, is a 20 yr old mustang, light riders and light riding only. She moves perfectly off of my leg, any direction I ask, I can back her around lots of different things (its fun to try obstacles) with just my leg.
I have complete control of her with just the halter, so no, I am not going to use a bit. Now if it was another horse, I would probably use a bit. I know I'm learning but I'm not an idiot either. My boss/trainer doesn't see anything wrong with it as long as I have control of her.
Of course I'm nice and I am always open to hear someone's point of view even if I disagree. I listened to his spiel once and he still won't leave me alone about it. I just ignore him and do what I do, but ya totally annoying LoL
