The Egg Butt and D ring were designed after the Loose Ring, without the Loose Ring Effect.
The Full Cheek was designed to not slip through the horses mouth, but should ALWAYS be used with the Cheek Pieces. This bit was designed to sit a certain way in the horses mouth at a particular angle, and can only be done when the Cheek Pieces are in use. When this bit is used without the cheek pieces, it is now sitting incorrectly in the horses mouth.
I ride in Egg Butt Cheek Pieces and D Ring Cheek Pieces.
You did better than me! One of the girls at the barn asked me and I just had to turn to her and tell her I have no clue!
I knew about the loose rings, I discovered a love for them when I got my TB who use to try and grab the bit but couldnt do that with the loose ring bits. I also like them for beginner riders as I find that they aren't as harsh on the horses mouth when the riders hands are all over the place.
So is the only difference between an egg butt and a d-ring the shape of the rings? Wonder why they have both types then.
D-ring is bigger and put more pressure on sides if you try to turn a horse. From what I read and which is logical. Eggbutt is more smooth where the mouth piece connected to the ring. I personally prefers it just because of that.
A D-ring has straight sides - So it puts more lateral pressure on the side of the face when turning - So that you are pulling the head over from one side and pushing it over from the other (Very exxagerated example, lol). It's really good as a first bit as it really helps clarify the turning aid.
A loose ring allows for some play in the bit, as well as preventing either the horse or rider just 'grabbing' the bit.
An eggbut has no play, and no assisting lateral pressure. The only time I really have a use for an eggbut is when one of my horses gets pinched in a loose ring and needs a double jointed mouthpiece - You can't get a D-ring side with a double jointed mouthpiece here. If you could, I would never use an eggbut. The others are better, in my opinion.
I much prefer loose rings over anything else. I heard that when you put pressure on the bit the rings have to move so its somehow less severe (?) I only heard that so correct me if I'm wrong.
That's what I had heard too, that the movement of the rings somehow softens the severity of the mouthpiece or the cue. I just like them because it is harder for the horse to grab on to the bit and brace.
