Were me, I would go with morphs that are likely to be middle of the road in value long term. Those that have traditionally held their popularity in the pet market.
Pied, clown, and albino seem to want to stick around with combo critters reaching high numbers. I would go with these recessive as a base with some popular dominant or co- dominant morphs mixed in. Already being at a disadvantage here with a super pastel male though. I would pick up animals such as albino Het pied, clown Het albino, pied Het clown, black pastel albino, Mojave pied, enchi clown, etc.; whatever turns your head with these recessive morphs mixed in. Try to buy as many visuals and as few hets as you can afford and plan your breedings to always have a shot at visuals and 100% hets. I would not by just a Het with no other genes and anything that was a Het would need to be 100% and a visual of the another recessive. All hets should come from a reputable source.
Going with morphs that are new and expensive now may turn into not so valuable animals in a few years once you are ready to start pairing. Go with reliable stuff that has proven to stick around.
Plan on 1 male to service every 3 females. This will give the male an opportunity to service all three females and have a week off each month during breeding season.
Good luck.
