If you can find some who is breeding AKC Showline dogs that are also doing well in Schutzund, then you may want to speak with them and go look at their dogs.
But I'm thinking you may have a search on your hands. Responsible breeders have specific goals for their dogs, and the goals of someone who chooses to breed and show for the AKC ring usually have a completely different set of these goals than someone in the German Showring. The very looks/temperment that have a dog do well in one venue are NOT the same as in the other.
If you truly have intentions of getting into Schutzund, I would find the club in your area and start attending/helping in their weekly sessions. Then looking at those dogs and talking to those owners.
