Basically what I have seen is that ever since the red stripes hit the scene lots of these other "stripes" have popped up. I can only assume it gives the other breeders an excuse to inflate their asking prices, but I see it as a gross missrepresentation.
The line of red stripes I am working with are the definition of a stripe... They have broken neck bands, completely striped backs, and striped tails. These are basically a line of normal stripes (that many of you work with), but these have the outstanding coloration and the carrot tail. The same rules apply that you would use when deciding if a gecko was an abbrent, jungle or stripe.
Lots of the other breeders, some very well respected, are marketing their normal tangs as stripes. They are doing this when they see that white line down the animals spine. If you look closely at every leopard gecko you will see that mark down the spine, it's just that the mark is more noticable in the hypo tangs.
You are right about the tang in your signature... while she is a killer hypo tangerine, she definitely does not have a striped tail. I'm really happy you asked this question. I hope I got my point across clearly, explaining things in writing is not my strong suite. Please let me know if I was unclear in any way, or if anyone of you have any questions.
I attached another picture of that female... take a look at her tail.
