Green is confusing. I think the original greens where in the bigger compatible group and I know that what TSK now sells as green (descendent of their original import girl that they used to call "extreme" but now call "green" and I believe is the source of their hypo mojavies) is compatible. But recently I've read mention of incompatible "green" line hypos but I don't know where those came from, who found them to be incompatible, and who is working with those "other greens".
