OP seems to have dropped it from the running but throwing this out there in case it’s helpful to others:
Our jumper has a PS of Sweden bridle that his previous lease human bought for him, albeit with a flash and not the high jump noseband. None of us (me, the trainer, my kiddo, or the horse) are crazy about it. The crown piece is not a good fit on this particular horse and it’s almost impossible to put on the bridle without catching the poor horse in the mouth with the noseband. But the biggest issue is that something about the design of the optional throat latch causes the brow band to unsnap while riding and it’s hard to fix without dismounting. It’s only happened to my child once or twice but it happens to me fairly often while riding the horse and happens to the trainer almost every ride. Given that it happens the most to the trainer, I’m guessing it has something to do with changes in the gullet area as the horse comes into a balanced frame that makes the snap come undone.
