The numbers! Oh, the numbers!
How many bulbs are you replacing?
The reason I ask, is because if you are replacing just one, I would not go with the 75% actinic/25% daylight... you would loose a lot of white spectrum.
I guess it depends on what color you are looking for. If you are happy with your current mix (sounds like separate 10K bulbs, with supplemental actinic), then I would stick with that. Especially if you are planning on changing to T5s or MH down the road.
I would think the 2-n-1 14K bulb with actinic would be too blue.
