I hear you on the "long week," Lakota!
To the OP: like others have said, I'm not the biggest fan of wonderbits, or any sort of gag, really. Some riders love them, I'm just not one of them.
You could try going to a snaffle and seeing how your horse likes that. My personal favorite is a loose ring french link, but of course it depends on the horse (my own personal horse HATES it!
If you really want to stay in a curb, I'm not of too much help as most of my experience is in snaffles. I do like the look of the Mylers, though!
But remember, just because your horse is gaited doesn't mean he has to be in a curb. I grew up where every Walker I knew was in a double twisted offset wire, with 6" shanks!
There are lots of great threads around the forum on different curb bits if you'd like more info on them, since I'm no help!
Good luck! Posted via Mobile Device
