Only you can decide what you want.
7 to 7 is kinda wasiting your male's breeding potentional, but that also falls on the females if they are ready to breed or if you will be bringing them up which takes longer with females than males. Get more females than males, and if doing het.s, get a female het. now, bring it up, then get the male when the female is ready. That's how I usually plan my future breedings with hets: what's the female gonna take so the male isn't just hanging around. (depending what you are going for and how the male may play into other things, there is obviously many exceptions to this as well)
Otherwise, you sound like you know your focus, just get the snakes that will get you there. If trying to get more snakes for your money, never doubt the use of a normal female when starting out (or even down the road). You can get a few close to breeding size for the price of a single morph and this can help get your breeding started if nothing else. Take the normals to a male of a strong morph and that can give a nice first breeding season until you get better genetics to work with in your collection. They are also useful for breeding out hets from a recessive male.
Now that I have more snakes, I don't fall back on normals as much except a dinker or two I'm playing with, but again, is a good starting place to bulk up a collection with females.
