honestly i would recommend attempting to see as many of the morphs in person as you can before making your decision. They are all more beautiful in person than they look in the pictures online, and it's easy to get into the hype produced by sooo many possibilities.
If you have a show or large breeder nearby that you can visit and see all their morphs, then you should visit them. Look at everything you can, hold a few, then go home without buying anything.
After a week, write down the ones you;re still thinking about or the ones you regret not having picked up while there. Then start figuring out how you're going to get those snakes into your collection - breeding or buying. Once you have a plan, buy a snake.
This approach gives you an educated start into your breeding project and mitigates the tendency to want and therefore buy everything you see right at first.
