I agree with the butter, the Butter bee is such a nice combo, and it will open the doors for a lot of really cool combos the next few years. . . after that, I would say the clown poss het ghost. . . only problem with that is you would have to hold all the snakes back to see if the poss het ghost gene proves out, then you could eventually work on a hypo spider clown. . . that would be pretty sick. Good luck, let us know what you decide.!!
