. . . since I don't have any trempers, I don't have any experience with his Tremper method - except if you include my stinkin' incubator flipping out and cooking the majority of mine last year (and also killing the majority of the eggs) . . .
That being said . . . manipulation of animals is done all the time. We dock tails of certain dogs - clip poodles to look like goomers - shape ears of Dobermans - braid the manes of some horses - etc. Shoot, when I was showing animals in 4-H there were a number of tricks of the show trade to show off your animals best attributes.
As far as Ron Tremper using heat to bring out the while in his animals - I say, more power to him. We would never know the potential of that gene - unless we applied HEAT to trigger that effect. Tremper albinos - white ones - are some of the most beautiful animals in existence. I think this fact is born out that most people have pretty much left LV' albino's go except in their use for PA's. You see very little market or clamor for LV albinos, while the tremper albino market remains strong. That tells me something - because marketing can only go so far. You still have to have a strong product - and white trempers are still the bee-knees of the leo hobby.
As far as temper-cooking tangs go - I have some suspicions. I have seen some 2nd hand accounts of people who have bought tangs from very reputable sources, which have gone "bad" (lots of melanin coming back) - after subjecting them to night temperature drops. That makes me SUSPECT (not prove) that some people are cooking tangs out there to take a short cut to SH's. That, in my opinion - is a different thing than temp-cooking Trempers.
That's why I appreciate people like Kelli, Robin, John Meltzer, and a few others I know who's tangs are nice and orange right out of the egg - cooked at 82 degrees.
Sorry for the rambling - but it's an interesting topic.
