First one hands down.
We have a mostly Russian mare that is incredible. She is extremely competitive and nothing distracts her attention from the task at hand. Her determination is amazing. She is a Nariadni grand-progeny.
I have a CMK mare that is a tank. Haven't started her in endurance yet, but she is proving very easy to train and has become a very solid mount. I never thought I'd see the day when I would say I trust her completely out on the trail, but I certainly have to take that back now.
