in line breeding you breed back to either side . if you like the father better breed daddy to daughter if you like the dame better breed mother to son . it just depends on wich side of the family you are trying to reproduce traits from .
x2...exactly my thoughts...The question is what traits do you want???If I want the mothers traits and capture some from the sire then I would breed a male pup back to the dam. A male pup that has the qualities you like.
Also If the dam is what you really like then get one of those pups and breed to an aunt or an uncle which would be the dams brother or sister...
you will get lots of variation at first so make sure to pick the pups as best as you can...
it might have been better to have bred the dam to a relative of hers that had the traits you liked and it probably would have gotten you there faster...
