				Originally I believe the whole idea called for ELECTRONIC ballasts. Most of the ballasts I saw used here were at best Hybrids.

 I had questioned the quality of the ballasts purchased at Home Depot.  They did not seem to give off the same amount of light that my Advance ballasts did. 
I have the Advance REL-4P32-SC that Burnabyreefer had said to use in his original thread on overdriving.  I believe these are true electronic ballasts.  I am running both T12 and T8 bulbs, but not mixing them on the same ballast.  
I am currently (not a pun) running at 2X so I have 2 bulbs per ballast.  So by removing one ballast and two bulbs I figure I could add one Workhorse 7 and 4 55W CFL in their place.
