The appalachia male is very dominant, and depending on how recessive the genetics of the female are they can end up rather overpowered. Pheno selection is the key, there, I think, and it is more important to run full packs of the appalachia hybrids if you are looking for the best. The current appalachia strains I'm running (keepers of SSDD, Elphinstone, and ECSD x Appalachia) all had similar plants in the packs, but most of those were green crack dominant plants that I didn't end up keeping. As far as my actual keepers go, they could not be more different in terms of smell, taste, or effects.
Contrarywise, the Snow Lotus is incredibly recessive, and every snow lotus hybrid female I have run has had aspects of the mother plant.
