nothing that knocks my socks off on paper.In first 3 gens there is just the very common Norhtern Dancer who is a mixed bag of talent and smallish/QH-y confo.More good uns if you get back to the 4th generation...but I would ideally like to se a horse I really like up closer than 4 gens. If you like this horse I would judge it more on the horse in front of you. Especially if it is to be a riding horse and not for breeding.
I see alot I like in the 3rd generation back -- Meadowlake, Bob's Dusty, Forli, etc. Even though we may not recognize the closer relatives they descend from a good pedigree. The pedigree is only one component -- the individual should stand on his/her own as well.
