I would stick with Icecap SLR reflectors, tested to be the most effective reflectors so far, and much easier to clean. As for the ballast...well...if you want to overdrive them with an IC660 ballast, you will still need another ballast for the last two bulbs (IC660 does 4 bulbs max). If you do overdrive the bulbs, be sure to add some fans/proper venting to keep the bulbs cool. OR, you can just use 3 of the 2x54watt Triad/Advance ballasts and not worry so much about heat.
