Iam using a bit like that for my bit fussy gelding and to my amazement it works great.Keep a loose rein and be light with your cues when asking him to turn and stop. My gelding was the same way with other bits chompping on the bit gapping his mouth and just plain unhappy. Now he likes current bit and no more chompping and gapping. Every horse is diffrent though so might have to try several bits before you find one he likes. I went through six or seven before I found one mine likes.
