Personally the female YB is way more valuable to me then a Bumble Bee male. Het hypo or not. Now, that's in terms of my collection. I think it really depends on which you'd rather have, whether or not one is technically worth more than the other.
Bingo! trade value is based on your collection and not what you can sell it for..
