hey y'all ,, as the titles says , whats the different ,, if someone can tell me that will be great!.. can't find anything on the internet ... btw ,, how come i also hear there is panda gold , but they look like a rtg .. is it just an name that the seller gives to get more money? well ,, from what i think about high back and rtg is that .. rtg only gets 4th level shine?.. and high back gets to 5th?... but how you tell them apart from a young age? 5-7 inches?
