I need some help choosing support splint boots for my rope horse.  I have a mare that I breakaway on that is not a fan of deep ground.  She does not interfere with herself normally but I have found when the arena is really deep or switch from hard (in the box) to deep (outside the box) she has trouble and wants to quit running.

I use a leather fetlock splint combo now with bell boots and think I need to make a switch to more support.  What are the best options that you have used that aren't too bulky and allow the bell boots to fit correctly?

I switched from classic equine to iconoclast and really like them. I feel they offer more support and keep sand out better than the CE and SMB
