My choice would be:
Females Ready to Breed X Males Ready To Breed
Pinstripe 100% Axanthic X Axanthic Black Pastel = to try for a Black Pin and luck out on proving out with an Axanthic Black Pin
Axanthic 100% Snowball X Albino 100% Axanthic = to shoot for the Axanthic Albino (Snow)
Normal 100% Axanthic X Axanthic 100% Snowball = Just to prove out the female and 100% and get a couple Axanthic females if lucky.
With hets I would not play "whos your daddy", I would rather try to prove for sure unless you have already bred before.
