In pure (photo) form it's in my opinion a straight 50/50 hybrid, with the auto livers using auto blues as the auto donor and the sour livers using sour crack as the auto donor, they're substantially more on the indica side in general but you can come across taller more sativa phenos - there should be test grows knocking around the mephisto forum as well as probably some pages back now I wrote the project details and what to expect from the sour livers in full - I'll be writing the other new descriptions tomorrow
