If you want consistency, there is only one way to breed: family breeding. If you want to play hit-n-miss guessing games, then make random crosses and mixes ... as ALL major breeders are/were family breeders.
It is the only way to fixate traits.

BTW, here are some more "pretty famous" dogs that were highly-inbred (all calculated @ 10 generations):

Gr Ch Zebo (7xW) ROM - 52%

Gr Ch Buck (7xW) ROM - 38%

Gr Ch Gizmo (7xW) ROM - 41%
