In using Silverback or any dog, the only way you know an offspring has finish is to see that happen or happening. Your odds aren't increased because the offspring is seal and from a litter where a dog with finish comes from. Most of my dogs are red, red nose so color doesn't play a part in the decisions I make. Seeing the offspring do their thing is the sole thing that determines which are bred and which aren't. You eliminate the guessing game about which to breed, but you still have to go through the subsequent offspring to see if what you want is there. My way isn't the only way to skin a cat, but it's the one I prefer to use to satisfy my own curiosity.

You are right in the sense that everything does decrease without the ability to keep litters. Invariably, you have to depend on people to give you THEIR feedback, and if they're not of the same mindset or an easier judge, then you simply have to take their word for it and hope for the best. If your dogs are going to people that seriously know what they're looking for/at, then things are a lot better for you as the breeder. They should be able to give you an objective view of the good and the bad of the offspring, and you will be able to make your decisions accordingly.
