To be more precise your bark solution was too hot. In this case it seems like you get bigger yield but there is lots of some oils and other gunk. I`ve played a bit with cyb`s tek and from my experience i can tell that better to do cold pulls. This way i get clean spice and there is no need to make re-x. Cold pulls give slightly smaller yield but not a big difference if you`ll recrystallize yellow spice from warm/hot pulls. If you want white magic i`d make some small a/b. And again from my own experience white dmt is MUCH better than yellow(in most cases i get harder experiences with this kind of spice) even not talking about orange...
