You really should have a serious discussion with the breeder of you puppy about any health issues in the lines. No line is perfect. I have heard of problems with some of the lines you mentioned but that does not mean your puppy would have any of those problems. Anyone who breeds dogs will have problems sooner or later. Some breedings are just a bad match and it is impossible to predict when problems might pop up.
