Best color temp for LPS?

[coralville]

I have a 45g tank with PC lighting, 2 X 96w. I'm currently using the SunPaq Dual Daylight 6700°K/10000°K and the SunPaq Dual Actinic 420/460nm lamps. I'm going to need to replace the bulbs soon and I was wondering if I should stick with the same type of bulbs I've been using or use the 6700K/10000K bulb and the 10000K/actinic 460nm ?

I thought maybe if I switched the bulb combo the corals may get more usable light. I have a frogspawn, 2 hammers, a lobo, and a plate coral. They look happy/are expanding well but not growing. I haven't been feeding them on a regular basis but I'm planning start a regular feeding schedule soon.

Any ideas?

For pc's I like to run one 50/50 and one pure 03 actinic, they give a nice crisp color
