Hi Friesian1 and welcome to the forum. what are friesians like ?
That's a bit like asking what apples are like. They seem to be a fad breed lately, so they can be seen in all types, quality and temperament.
What type of riding do you do? What would be your plan for a Friesian? Many don't like their ride at all. Some who come from QHs for instance, are not used to having a neck and head way in in front of the rider.
You should visit as many responsible breeders as possible and get a feel of the breed. Get aquatined with their registries and know what to look for. There are tons of Friesian and Friesian crosses about right now. I've seen some which received the good points from both parents, but many who are a mess of a cross.
