Best to the Best until the cross fails to produce.......then find out which link is the weak one. Typically just one.
Some......are just not genetic producers or cannot reproduce the desired traits to the offspring. (Mostly its piss poor judgment of quality by the breeder.....to an inferior dog)
If you have a hot to trot male or gyp.......take the time to find another match that is either as good....OR BETTER to breed to.
Can a line littermate that is the lesser dog produce a great batch of pups over the better littermate ?.....Sure.......but rarely consistently. There is a reason he or she is Second best.......and that in my book is called (Lacking)
I never bred second best on purpose so I wouldn't know from experience...however...it has been written by others many times...
