I'm also curious about bits...Willy's in an egg-butt snaffle, but he chomps it really hard sometimes. He also pulls on it quite a bit (no pun intended)...his teeth were just done in April. He usually chops it really hard if we're standing still, so I don't know if it's just an anxious thing, or if he is really over it...was thinkg about a Happy Mouth? My friend uses one, and they look so much softer on the mouth than metal.
Thanks for the post, Jubilee...you're mare is quite a hottie 8)
