Yes you are right high standards and consistency . I don't know why some people have wide swings in type. I guess that's their thing.
for myself I'll take a balanced gene pool and pull virtue in from both sides of the pedigree everyday of the week. hopefully removing fault as I do that.
The phrase " balanced gene pool" is "the middle of the road".
A balanced gene pool is mediocrity. If a gene pool were balanced, they would have the same virtues on each side, and you woukd not remove faults, because they would be fixed into the line. That is what the middle of the road is. You could have a clean gene pool, and have more consistency, and less wasted effort.
