At my barn, we have 2 Friesian/Saddlebred crosses. They're absolutely breathtaking in their pinto coloring. The older of the 2 will be 4 years old this year. He's being trained in hunter under saddle. Omg, he is an amazing mover! By far and away the smoothest canter I've ever ridden - that's a lot of different canters! - and his trot is just as pleasant. I can sit his trot without pain or post it with minimal bounce. He's a great mover and SUPER sweet. He loves to give kisses and is wonderful with kids. My 6 year old daughter has been helping his owner (a friend of mine) clean his stall, brush him, and even bathe him for a year now. Now that my daughter is more careful and more experienced around horses, the lady who owns him lets my daughter lead him back to his stall (with supervision, of course).
She has a just-turned-2 year old filly that is being started now and she's just as sweet and loving as her older brother. They came from the barn that started the "Georgian Grande" (sp?) registry back in the '70s (I think). The filly is a more animated mover and we're thinking she'll do saddleseat. She's 2 years younger, but already the same height as the older one. My daughter also helps clean her stall, brush her, give her treats, and anything else that a 6 year old can do with a horse.
I've never had a bad experience with either of them. Maybe they're an exception, but I love their colorings, their builds, and their temperaments.
