Not sure if I am posting this in the right spot or not...
Anyways, I have a 5 year old TB mare who is quite heavy on the forehand at the canter. She goes quite well at the trot and is very light on my hands. However, when we go to canter it's another story... She becomes very heavy on the forehand and will nearly pull me out of the saddle. If I lessen my contact she picks up a ton of speed.
I have recently started taking lessons and the trainer said that my mare is grabbing the bit when we canter making it impossible to tell her what to do. I am currently riding her in a loose ring french link snaffle. When I had a regular snaffle on her she would constantly root because she didn't like the nutcracker.
The trainer I have started taking lessons with told me that I need to get the exact same bit only with a D ring instead of a loose ring because it will help my mare to not grab the bit.
Does this make sense? My thinking is.. if it's the exact same mouth piece, how is just changing the ring going to do anything? I don't want to waste my money buying another bit that will have the same functionality of one I already have.
I also had a friend suggest to me that I use a level 2 Myler with a medium port to help lift my mare up. I don't know a lot about bits and I don't want to put anything too harsh in my mare's mouth.
Any suggestions or input would be helpful! :)
