Oh trust me, I am putting it off as long as possible! He really does perfer his snaffles, hehe. I am going to do the same thing that you do with your horses, after doing what you advised (I hope that made sense). I perfer snaffles myself, so he will school in that at home after he gets used to the tom-thumb when I move him onto that.
Just wanted to add two things... One, yeah, he is on the forehand pretty bad normally, that is one of the mane things we will be working on once im riding him again. Two, I am so, so in love. =,]
You can never take a Thoroughbred away from a horse crazy girl.
