I don't believe as many people as you think here in Australia will cross there animals, and certainly don't think it is the way the hobby is going.
After all we have what most of the world don't, pure locality specific animals, many of which carry there own unique traits/genetic defects ie. striping, hypomelanism, albinism etc etc..
Of course there will be a few that just can't help but try to produce a world first, ie. A bredli x albino darwin or a
albino darwin x gtp , there is an appeal about these animals to, but it's not something that personally interests me although i can respect the animals for there uniqueness.
I don't think Sunrise reptiles should be criticised for his work with crosses as many europeans and americans who don't have access to our locality specific animals will work with such animals.
After all Sunrise is declaring them for what they are, crosses and good looking ones at that.
My hope is that the people in Australia that do decide to cross, do so in a responsible manner and don't try to sell off young as something pure when there not.
