Okay, so I'm looking for a new bit for Desi. We mainly event, but we will be doing a little Dressage and Jumpers for training/fun. When we go xc jumping she is more excitable (she loves it!), so her eggbutt snaffle doesn't really do much good. She breaks at the poll just fine, and she's amazing on the flat (just a little forward moving, but once you get her warmed up she's awesome), jumping she likes to rush the jumps, but we are working on that. On xc she will go to the jump fine, then when we and, she will take off. She has problems turning on hills and likes to turn to the outside when circling.
I like this bit. Myler Low Port Comfort Snaffle Horse Bit MB 04 | Dover Saddlery
ETA- I've used the bit above on young, green horses and I love it.
