I have the brochure up in the tackroom (came inside the blue packet with the bit). WIll try and remember tomorrow to check. Am nearly sure there are bridoon bits anyway, not sure about the weymouth.
Flo loves her new double jointed happy mouth, not sure how it can be bad for her if she likes it??
Checked in brochure and do weymouths in quite a few different types of mouthpiece (straight/single joint/revolving joint etc), and all the loosering snaffles can come with dif sized rings (which is the same as bridoon really isn't it - just a snaffle with a smaller ring).
