Yep, you are right, wasn't long ago the double ended 10K HQI bulb was the latest rave.

I am going to go for the radiums, but I might try a M135 ballast for a longer bulb life, If the color is too blue I might throw in a Iwasaki 250 watt in the middle to whiten it up and provide the growing power for the corals.
