CFl Flowering Question???

I know that Day light CFLs are best for veging, which im currectly doing and Soft White/Warm White are Best for Flowering. So my question is Would it be fine if i flowered with Half Day Light and Half Soft White???? or should i stick with strictly soft whites?

Most people do all 2700k-3100k(soft white) for flowering and all 5500k-6700k(day light) for vegging. But I am under the impression that using a mix is the best so thats what I do. Either one will produce equally good results.
