When I am looking through import babies I always look for female dinkers and we usually breed a co-dom combo into them when they are old enough. If they prove out, not only do you get a shot at making a few different combos right off the bat but if you get a male baby, you can breed it back to mom the next year to see if there's a super form. If they don't prove out (which most don't), you still get a worthwhile clutch and another female for future breedings.
