I think the only people breeding a normal male is someone who is breeding just to breed with only a normal male and a normal female. The only other people who breed "normal" males are people working with serious dinker projects.
I personally don't see a lot of breeding worth in normal males. Since males can be bred to more than one female, it makes sense to breed a male with the most genes so it passes those genes onto the babies. If you breed a normal male...the only morphs you'll ever get is if your female is a morph. But then again, that's a waste because it's so much better to breed your morph female to a morph male to make more morph babies.
