grackle or combination noseband (see townfields saddlery catalogue) - its a combination between a drop, flash and grackle and worked wonders on a horse of mine who crossed his jaw something chronic.
Drop noseband. Incidentally, Star's bit is a 14mm. and she crossed her jaw like mad to evade it. A drop noseband helped the situation and now we are back in a cavesson.
just got a new myler bit and its thinner espically because he's got quite a big tongue so it shouldn't be that. thanks 4 ur help.. will try a grackle i think.. or a drop.... hmmmm.
