ERIN, I have a mare that is like this. Works great at home in the Little S. When I run her though, I found that the Janet Stover Hack works great. I have used the Ed Wright Hack, and it has a bit(pinch) place. It was not as much control as the Janet Stover Hack either. I really like mine. I can really set her in the dirt.
Even though I didn't do it last Sat. at Stephenville, only because I put a wonder bit on her, da............, I'm to blame.
I think you can find this hack at most of the tack stores around the Metro plex area. I got mine off Ebay. Hope this helps. If I am ever at a race where you are, you are more than welcome to try it out.
