Maybe breed towards the harder character of the birds or maybe intoduce a newline to your family (traits you like from another family)

Keith:
If you have hit a wall in your family of birds, take your birds out with a complete outcross or a bird from your family bred a different way. I would use a Hen not a Cock, A hen would not be as dominate as a cock would be....Glenn

If I cant find it within the family,I would do what Steve suggested and introduce something new into the family.

Here is part of an article I wrote called "Can We Breed Better Spinner" that touches on Vigor. You can read the rest of it in the reading room.
If you have achieved a highly inbred family of quality rollers, how can you make them better? With an inbred family, to produce even better young birds, you need to introduce a new super gene that your own family of rollers don’t have, you need to add something extra. This is when an outcross is relevant. It will introduce new genes into an inbred family of rollers. This introduction will produce a roller that is superior to either of the parents. It is known as hybrid vigor. It generally occurs when new super genes are incorporated within the genes of the highly inbred group of individual rollers.
Be careful, hybrid vigor can be a very fragile concept. When it occurs within a loft, and unless a careful breeding strategy is carried out, it can easily be lost. It happens more often and frequent than you think and explains why fliers can have a tremendous season or two, winning prestigious competitions, and then sink into the background and never to be heard of again. The simplest solution to maintain hybrid vigor is to keep together the pairs of rollers that produce the better rollers and not introduce any outcrosses. It is essential to set up two lines of breeding to increase the number of pairs that produce the magical hybrid vigor. The producer hen must be line bred back to her father or brothers but never to her sons. The cock must also be line bred back to its mother or sisters but never to his daughters. The resulting offspring from the two separate lines can then be mated and hybrid vigor will reappear.
