Help me pick my next MH bulbs

[unttrmptplyr]

Right now I'm running two 400watt MH (PFO ballast) XM 15K bulbs (SE), and it's time to change them out. I'm considering trying a different brand and just wanted to get some feedback from the board. I will also be supplementing with a Super Actinic and a 454 VHO from UVL with an Icecap ballast. I want more pop and fluorescence.

Thanks!
