I wouldn't be without normal females.... some of the traits on those are at times just as desirable as morphs (Depending on what your breeding for).
I have light colored girls, blushers, odd dinkers etc that I want for select projects. At times, with a dinker.... you just never know what your going to get from her.... unlike a morph where you know what to expect.
And normals are beautiful too!
That's my 2c
