What bulb would you run with a pfo ballast?

Looks like the Radiums are out. I have a dual 400 watt magnetic ballast. I love the radiums. What is my next best bulb. Running xm's now and they just don't have that pop like the radiums put off.

I've always loved XMs. I know my dad has always raved about his Coralvues... and I've seen several comment on Phoenix bulbs as well.
