Bit advice please. Im stuck

[Degan]

Right I'll try not to make this into a waffle

He was in a Dutch gag but I have found that he doesn't like the poll pressure of this. So for schooling I had him in a fulmer snaffle, which was good for a while however he likes to test things so Ive since put him in a fulmer cherry roller which he is going brilliantly in . . . in the school.
However doing fast work he is very strong (Welsh D built like a brick . . . you know the rest )
So here is where Im stuck, I dont want to go back to a gag as this didnt really work anyway and he isn't great in a Pelham. He does respect the curb but he still isnt happy with the poll pressure that comes with it.
SO can anyone suggest what else I can try please

Was thinking of a Kimblewick so I have the curb but the shorter shank (than a pelham) so less poll pressure (but still some . . hmm this is where im stuck)

What other bits are there that have a curb but also a mouthpiece that promotes mouthing (as he really mouths on the cherry roller)

Sorry that did turn into bit of a waffle.

Thankyou if you can help

How are you with two reins?

Keep the fulmer cherry roller or try a copper roller.

Instead of poll pressure try nose pressure.
Either a scrawbrig or a drop noseband set above the bit with reins on the rings.
Use this as an oy! when he forgets himself. I've used this combination with good results.

I think whats important here is to, instead of increasing brake power, you teach the horse how to stop. Its not just about pulling the horse to make him stop, you have to teach him what the aids mean. I always like to teach a horse on a long rein, western style. This way they never learn to lean on you. Only when ive established good brakes and stearing, would i ever pick up a contact.
Ideally what you want is as soon as you ask for a stop, the horse softens his mouth, flexes the poll and stops immediately, and as soon as he does, you totally release the pressure. You should be able to stop from any pace, anywhwere because the horse understands what the aids mean. Ill put up a video of someone teaching the stop and reinback, as im sure he can explain it a lot better than me.

I personally prefer the second video. When the horse learns what the wow means, you wont need no strong bit on him. Hope this helps.
