I really have no idea about Arabian lines (a person who knows a lot is WSArabians, I think, she doesn't get on much but she gave me a full, in depth, run down on Lacey which was super interesting) but I thought I'd let you know that Lacey and Brandon are related!
Witraz is a pretty common Polish sire so tons of Polish bred horses have him but he makes Lacey and Brandon related. I have no idea about Lacey's mom's side so they could be even closer than that! haha I can't remember what I know about Witraz but I think, if I'm remembering correctly, he sires very athletic horses that can really do pretty much anything asked of them. He's a good one to have repeatedly. :)
