Personally, if you're buying a foal for jumping I'd look for more jumper lines. Generally speaking jumping lines enhance dressage horses and dressage lines detract from jumpers. The sire only got a 129 on jumping, which is good, but not spectacular. The dam's sire is a dressage horse with dressage lines (Hanoverian) and the other side appears to be TB??
I would look at jumping horses you like, look at their lines and then try to find foals with these lines. If you are open to buying from Canada I also personally know a breeder with some gems and a stallion jumping 5' at Spruce.
