Dang that is one long shanked highport. I wouldnt throw that in horses mouth unless he was running everything over. I wouldnt risk tearing his mouth up. That's to much step up too fast. that's a very nice way to ask a horse to rear with you. Personally I like the bottom bit you posted. Around here I have talked to many trainers and one in particulat uses o-rings on every horse. He takes the nuttiest of brats and can calm them down to sprint a pattern in an o-ring
Yea, if you put that bit in the hands of someone who doesn't know what they are doing with it. Hence why I specifically said to enlist the help of a trainer to soften his horse and get him to accept a bit (provided his teeth are fine). ANY BIT that isn't used properly is just asking the horse to misbehave, including rearing. And I don't think you should wait to correct the problem until the horse is "running everyone over". That's way too late.
I was riding my horse Red mostly in a snaffle or a Wonder bit before I took him to this trainer. Pretty mild stuff. But I was having to PULL on him to get a reponse. And the trainer I took him to slapped that high port on him. And he is SO SOFT now. It is amazing. He bends and flexes beautifully, and stays nice and relaxed. All with just the slight lift of the reins.
No, that high port isn't going to be for every horse. But neither is an O-ring snaffle. You've got to match the bit to the horse.
I posted the ported bits because they are working fantastic for my horse. I would have NEVER tried those bits on my own. But I got help from someone who knows what they are doing and showed me techniques to keep him soft, and he's doing great. And he would never have gotten there in an O-ring snaffle. Wouldn't work for him.
And really, the shanks are not that
long on either of the ported ones I posted. Not a short shank, no, but they are pretty standard "normal" length.
The bit doesn't "tear a horse's mouth up". The hands holding the reins do.
