Allison, my horse prefers the flat link, he is strange! I prefer the oval, myself, and am using an oval link eggbutt to mouth my filly (fully Aurigan, even the rings, cost a fortune). But what works for the horse, works for the horse, so ideally I would have liked to have gotten something with the same mouthpiece as his eggbutt snaffle. My budget didn't extend that far.
It seems ebay is a wonderful way of finding bargains, if this bit is as nice as you say... I paid just under $40AU for it including postage from the UK. And it's brand new, never even seen a horse. My first ebay experience, and assuming this bit arrives as described, definitely an experience that'll have me going back for more.
I don't think my kimblewick has that much leverage, if any. No slots (it's got them but I only use them at shows or for XC), loose chain, he pokes his nose in it (mouthpiece, he doesn't like unjointed bits, but I don't have a choice because a jointed curb isn't allowed at my level of competition), so the rein ends up being quite high on the ring. The physics of it are very similar to the baucher because of how my horse goes when it's in his mouth. But, in my subconscious, it's a strong bit, and because of that, I don't get so nervous. That's what I want. Something that is strong in the depths of my mind, but that he can cope with. Too strong and he loses his head because he HAS been bitted up and bitted up and bitted up in the past with a rider who had really bad hands.
I am restricted to bits that are allowed in dressage competition, because I have a bit to jump in that I am very happy with, and I want to get more seriously into eventing... but I have to find something that gives ME the confidence I need so that I'm not worrying constantly about him getting out of control. That's what causes it now, I get nervous and revert back to old habits which he couldn't cope with then which caused the issues (him bolting) that I'm now scared of. Which causes him to bolt, which just perpetuates the nervousness.
So please don't tell me that it's not what I want from a bit, because I'm not doing this to control HIM... I'm doing it to control ME. That was the reasoning behind the kimblewick, even though I could have (should have) worked through the issues we were having in a snaffle... I was nervous which caused me to drop him and caused him to do whatever he pleased. Which was bolting at jumps, which he still does if I drop him. He gets tense and rushy on the flat if I'm nervous, which I am A LOT away from home due to previous issues I've had with this horse and others. We then have a dodgy dressage test, which sets me up for nerves in the jumping phases, and sets HIM up, therefore, to fail.
I need to find something for ME, not for my horse so much!
