I was just looking online at Xrays of horses with bone spurs and calcium deposits on their jaws. One of the captions said something about the horse evading the bit. A bone spur might show up as a small bump or it might only show up on an xray, but after having had one myself, I just know they are painful and I feel for the horse which has a bone spur where the bit rests.
In the OP’s case I wouldn’t use a twisted wire, not necessary in my opinion.
I do own a twisted wire but it very rarely gets used. It is one of those bits that doesn’t get used on a regular basis, it is one that I use for a short while whether it be 20 minutes or two days then go back to a smooth snaffle.
I use it on horses that have a habit of shoving through the bit when I use leg, just enough to break the habit, the immediate response of wanting to lean on it, then I go back to the smooth. It is just a habit interrupter. Short-cut? Some would accuse me of using it at as such. But if the bit creates a different feeling that causes the horse to change an automatic habit to think about what he is doing with out pulling the piss out of him but rather he pulls on himself and figures it out on his own, is it bad?
Just a comment on cutting horses as it was mentioned earlier.
Finally the cutting horse trainers are figuring it out that the broker they are the better they cut. It only took how many years to come back around? LOL
But anyone that I worked for would of fired me if I loped on the wrong lead and not paid attention to how loped the horse was according to what he needed to perform. Some horses require more than others, some are show smart and act like they are ready to show but are as cow fresh as if they just walked out their stall. The difference between someone who just wants to lope horses and one that wants to learn and show well. Monotonous as it may be you still have to know your horses.
