I like the backglass with LEDs, I really can't see a reason to have them with incandescents... the artwork looks 100x better when you color-match or just use plain LEDs because they are so much brighter and light them much better. On the playfield I can still understand the appeal of traditional incandescent bulbs. Those whites are overpowering, eek!
I'm going to experiment with colored pops soon since apparently nobody has ever given that a try on EMs?
