Impression: Well I have not been able to play in the lower playfield yet but my impression is better than what I have gathered in the past playing this title at shows. Its fast-fast-fast which is what I like in a game. The few examples I have played before seemed slow and ponderous. Glad I had not written this one off as one I was keeping an eye out for.. but it was close.
Backglass now has Comet retro in warm white, the playfield inserts are retro natural white except for the green and blue inserts which have green or blue LED. The main playfield GI has clear dome retro warm white bulbs while the lower playfield has 5 LED white towers for GI illumination. Poppers all have 2SMD LED natural white.
My aim is to always look somewhat stock with just the slightest pop.
