Most registries have a jumping direction versus strictly hunters, or are largely focused on producing jumpers such as BWP or Holsteiner versus KWPN which does have more specific breeding directions such as dressage, hunters, jumpers, harness and Gelders. KWPN NA does not have any full TBs with approval to my knowledge however. Regardless of registry, if one is trying produce a horse with an intended purpose, it’s best to use breeding stock proven in that direction, especially if trying to produce a stallion prospect. The options for full TBs standing with the major registries is incredibly small, is geared more towards jumpers, has fewer that can consistently produce nice hunters. This was my point a few posts ago - this seems like a backwards endeavor if the goal is to produce a stallion geared towards the hunters breeding direction with WB approval.
As far as pedigree, the TB stallion OP has recently posted has very limited horses proven in the jumpers breeding direction on the dam’s side which is relevant to registries when approving stallions (when going the route of approval via inspection/testing versus a horse proven in competition). The stallion also doesn’t exactly have the movement of most competitive hunters IMO. The stallion is largely unproven. I think OP would be much better served buying a horse on the ground versus the current route.
ETA : probably worth saying I’ve come in and out of this convo quite a bit so apologies if I’m repeating myself.
