I just ordered the 2.0 kit today, so I will be joining the 2.0 club soon. I want to thank in advance everyone who has posted so much helpful info in this thread. Drilling into my game is going to be, well, terrifying.
My game has had lots of light board problems all along. I currently have all buffered, 7.5v boards. Not sure why some games have more issues than others, maybe it's the weather in different locations, as it seems to be static related. I do suspect (can't prove) that most games with the non-2.0 system will have issues eventually.
