CFLs - 6500k or 6500/2700k

So I am growing one plant with 182w of 6500k cfls and I'm 18 days from sprouting (check it out in my signature!!). Two of the bulbs are just 13w and I am thinking of replacing them both with 23w 2700k bulbs (I have 4 not currently in use). This would increase my overall wattage which isn't exactly neccessary since I'm just growing one plant, but it would also mix in some red light. My node spacing is really dense so far and I'm thinking it might not be bad to try and stretch it out a little bit. My question: is it better to veg with 6500 exclusively or are there benefits to adding 2700 bulbs?

never can hurt to add a few 2700k but my opinion kinda a waste a light when u could have one or two more 6500k

I know most people don't use CFLs so in order to appeal to more people, has anyone used other mixed spectrum setup and seen good results? Maybe simultaneously using MH and HPS, or LEDs at red and blue wavelengths?
