Yes
@Trewsers you have to clip it through under the chin. You mustn't clip on one side only or you pull the bit through there mouth if they are pulling on it being numpty.
You could also thread through from the side you are standing, up over the poll and back down the other side and clip onto the bit.
I like using the caveson and actually prefer it. I prefer not to touch the mouth when lunging. Use it for riding. I have wondered if lunging on a bit hardens the mouth.
The caveson is great on chunky and he respects it. Billy cannot tolerate it though, due to his headshaking. He is actually worse even if i put a nose net on it. So i had to resort to a bridle with billy. But i removed the nose band. I have an old bridle that is no longer safe for riding with so i repurposed it just for lunging billy with. Although that wont be happening anymore because of his leg. Its just too much even kept out on a large circle. I used to swear by lunging if i could ride. It was my go to in the winter months to keep the horse chilled. But when i questioned his soundness the most is when hes being lunged.
The inhand stuff ive done has just been in headcollar. Ive just been doing the inhand clicker stuff with chunky.
Long lining is actually pretty easy.
The biggest thing is right length reins and desensitising round the back legs.
I was taught for safety before i ever put down parallel to the body and near the back legs to go over the withers and desensitise the back area for several weeks first so if the horse does panic its not made worse by it going round back legs if they whip round on you in a panic.
With the driving the horse gets both the reins over the back and the tracers running parallel to the body.
