Personally, if I was running a 250w over 30g I wouldn't be overly concerned about the PAR of my actinics because your PAR should be fairly high already - depending hugely on what brand and type of ballast you're running though! So I would probably go with a pure actinic and use the UVL Super Actinic, or possibly the KZ Fiji Purple (not pure actinic) depending what color preference you like. Both will make the colors of your corals pop, probably the KZ a bit more so. If you want to pull the light bluer than that I would suggest the ATI Blue Plus. It's all personal preference when choosing color though.

Side note...if you're wanting an SPS dominated tank, I would suggest not having softies in the tank. Softies release toxins as a way of chemical warfare, and SPS are particularly sensitive to it. You can run a bunch of carbon to absorb the toxins, but large amounts of carbon seem to decrease polyp extension in SPS. So it's kind of a catch 22.
