Wow I read that whole topic by smrobs and it was really awesome! Now I totally understand that the harsher bit isn't meant to make the rider have more control, it's to look like they have the same control with less exaggerated hands! Now I understand the importance of the bit and how to use one CORRECTLY. Hey- I'm learning here. I'm only 13, I've got time.
So I think I'm still going to switch, because smrobs also said that she hated the tom thumb, and I think it's the cause of some of Putts's confusion lately - but instead of going harsher, I think I'm going to go with a much milder bit. Perhaps a snaffle, but also maybe along with a Sweetwater?? Because I've read that they are pretty mild for a curb. And I definitely need a curb for showing.
