Noah, no need to apologize...I do respect and usually agree with how you think...
I will give this example
I purchase a well bred basset hound and would like to train him to run against the greyhounds and I am very rich. I hire the best dog track trainer and I spend millions on training and feeding my dog.
You have a proven line of racing greyhounds and after a year we meet up and have that race.
It doesn't matter how much money or that I had the best trainer in the world you know the end result. The greyhound won and my Basset is still a slow Basset compared to the racing dogs but might be the fastest Basset around.

Either way he is still a cull when it comes to racing.
I bred hard hunting long range hog dogs.
Now I am going to focus on breeding gritty stop a hog quick type of dogs. The type of dog I envision is a dog that will basically run a hog a long ways if needed but should stop it at the first oppurtunity. I think that these dogs will not have that cold nose but I will be looking to get as cold a nose as possible.
I think that the average dog can smell about the same but it is genetics that decides whether a dog responds to the scent or not. Strictly my opinion, just my belief.
