  This sounds more feasible to me than to try to hold the pups until they are 16 weeks old and testing them yourself. Those I am not holding back for show potential are sold on spay/nueter contract. Those that I am holding stay with me until they are at least 6 months old which gives me time to have them tested for elevated Bile Acids as well as having all the other tests and evaluations that need to be done on them. Trying to eliminate LS by testing and than altering all of the dogs that either produce a pup that test positive or test positive themselves is a bit overwhelming to me, kinda like slaying a dragon. If it is polygenetic than what is the chance of the four genetic components coming together again to cause the same problem and are there any none genetic issues that are contributing to the problem? There are so many questions yet to be answered!
