When it comes to het I can see myself buying a possible het female however I would not buy a possible het male unless it did not matter to me if he turned out to be normal.

Now if I have a specific plan, I spend the money and get a 100% het male rather than buy a possible het male. (Het pied go for $150)

Imagine you invest 3 to 4 years of your time (probably even more) and than discover that the possible het is in fact a normal male meaning that you are not any closer to your goal than you were 3 to 4 years ago.
