Let's play "recommend a bit"
I am not the strongest rider. My inclination, when something goes wrong, is to curl into the fetal position and/or pitch forward. I'm working on this. Meantime, I have a lovely young horse who has a tendency to get a bit flat/on the forehand and to pick up steam over fences. I need a bit that gives weak me the ability to apply some breaks.
I had been riding him in a Stubben EZ Control D-ring. Which gave me, contrary to the name, absolutely no control and certainly no breaks. Before that, I had him in a Pessoa Magic D ring. I like that a LOT better but it didn't give me especially great breaks. Better than the EZ control, but not what I was looking for.
Recently I switched to a Happy Mouth 3 piece full cheek (as a general matter he always seems to be better in 3 piece bits). He likes this bit a lot and I love to flat him in it. He's forward, supple, happy, and responsive. He jumps okay in it, but it doesn't give me much in the way of breaks and he does blow me off and drag along when he wants to.
So I switched to the Happy Mouth 3 piece elevator, which a lot of people at the barn have used at various times with success. It gives me the breaks. For the first time ever, I have the breaks. But the horse CLEARLY resents it. On the flat he starts curling up and getting behind the bit, and at the canter he'll sort of be collected in front but trail out behind, rather than being truly leg-to-hand (the way he is in the full cheek). Over fences, I have those break. But I also have a horse who's starting to suck back on the approach and is getting very amped/irritated.
I know the moral of this story is that I *have* to ride better with my seat. I know that. But in the meantime, I'm searching for a bit that will give me some control so I can actually ride the horse. So... what's between a full cheek and a elevator for a horse who gets strong and blows off the aids. It doesn't have to be a 3 piece or a happy mouth (I actually hate happy mouth material for bits) but the horse DOES like those two things if that's a consideration.
