Hey! I have a mare that used to rush at the jumps, I started by using a elevator snaffle! we had a fall and the snaffle broke so I started to use the Pessoa snaffle and I'm loving it! Both with 2 reins (one in the normal ring and the other one on the lower ring) It allows me to use as a normal snaffle and just when she tries to rush I use the lower rein!
Hope it helps
I’m a hunter and use a French link Pelham and it’s allowed flexibility with how harsh it can be with the curb chain, but also allowed me the control if I needed it since I can put slack in the curb rein which then turns in to pretty much a basic snaffle when he’s being good. But it does take quiet hands because it can be a harsh bit in some circumstances.
