Curious question to follow up. Out of these Hypothetical scenario breeds that make up your personal preferences............How many are running exactly that breed or cross now in a full pack without other influences?
myles...that's a good question...some folks run 4 or 5 dogs of one breed and 1 walker or hound cross...

hmmmm...that kinda says something about them other dogs...lots of good me too dogs will follow a good track dog to hell and back...one good lead dog can make a whole pack of me too dogs look awesome...
I like a pack of 5 or 6 mt curs that don't need a catch dog to catch a big boar...that is what I used to hunt and it seems to be hard going repeating what I once had...
having said all that...if a man isn't serious about breeding a type of dog that does it all...then a mixed pack will work and sometimes be the best way to go...one good track/find dog and a couple of good me too dogs that can really stop a bad runner is not a bad thing to have...but that is not my style...
