Just for the record here, the "Ultra Hypos" I bought came from Mike Falcon, who swore up and down to me every time I asked him that they were PURE corns. And when I purchased the original GoldDust corn that Mike Shiver was calling "Amber" (

I'm not sure when and why the stories might have changed at a later date, but if a story changes midstream, then you simply have to conclude for your own self that if lies have been told, WHICH of the statements made are actually untruthful. And, of course, WHY, if an original claim has been recanted, why was it recanted at all? Are there motives at work here?
I guess what it boils down to is that there is nothing really wrong with hybrids. It's people who are at the root of the problem because of the potential dishonesty that could cause people to make their own claims that they BELIEVE are true, and in so doing work with animals that had the truth been presented, would have made different choices.
So I have no claims to make as to who has told what truths, if any. All I can say is that in the fair number of years that I worked with Ultra Hypos and GoldDusts, I never once got any hint of any clues that such animals were anything than what they were claimed to me to be. That doesn't mean that I don't believe anyone would lie to me. Quite the reverse, actually. It means that I have reason to doubt EVERYTHING anyone said to me, and choose to believe whatever evidence has been apparent to me. Which may or may not have anything at all to do with reality. Lord knows I have gotten animals that I later determined to have had their ancestry obscured with lies. And I dumped them QUICKLY after making such a determination, letting the recipients know my thoughts about such animals.
All we can do is try to do the best we can with the information we are able to get, I suppose. And take everything someone who is trying to get your credit card number for payment says to you with a BIG grain of salt.
