Opinions and /or experiences with SOF's. Soundness issues, temperament, running style???

We have a daughter in our broodmare program, she is a little bit of a hard keeper but is easy to get a long with. She has produced some nice babies by our CS Voo Doo Frost the only problem we have heard back about them is you have to be a really good rider to ride one because they are so quick they will get out from under you. There is a young lady who has been doing really well with one of them. we are very proud of them both
