Your best bet on reflectors is Sunlight Supply TEK reflectors. They sit very close to the bulb using metal clips (so they don't slip like the plastic clips) and are narrorer so you can fit more of them under a hood.

I have both the CoralVue and Workhorse ballasts. The Workhorse is easier to wire in my opinion.
