So I currently have three different bits and a two year old stud colt. I was given a curb bit and a d-ring snaffle with the purchase of horses in the past and ended up buying this bit at tractor supply last year when I was starting another 3 y/o stud (my first horse to really train. He wasn't truely green, and had been ridden but I just tuned him up to sell him) : Milepost Sweet Iron Breaking Horse Bit - 4007559 | Tractor Supply Company
. Anyway the colt in question, I've had since he was born and trained him from the ground up. Some may say he borders of more of a pet than a horse but I made sure he learned correct ground manners and he's very eager to please. I want to use him later for a barrel pony, and started working on ground work last year. He accepts a saddle just fine (no weight yet) and doesn't mind having a bit put into his mouth. I'm wondering which bit would suite him best? I started off using the one I bought at TSC last year, just tack him up 5-10 minutes at a time and walk him around to get used to it and worked on neck reining then untack and round pen him awhile. This year I'd like to work on ground driving and other things. I put the snaffle on him this year and he was ok for it awhile and then went to constantly chewing and biting on it. Just wanted your opinions on a good bit for him, if I need to go buy a different on or try the one I bought again?
