Knowing what you already have would be helpful in making that decision..Also with that much money you could buy a lot more than 3 snakes, but with that being said a few base morphs that i think can never go wrong are the pinstripe, lesser, spider, mojave, and yellow belly. If you're going for combos tho, I would say pastel yellowbelly, BEL(mojavexlesser), and a spinner.
