Two of my friends have Tron with LED flipper buttons and must say they play much differently than stock. When I first started on them, I felt they would bind easily when not pressed straight in. After hundred's of plays, I'm used to their feel now. I picked up Tron a week ago and it is tough to go from stock flipper button play to LED button play. It looks like some of the guys that go the LED button route do all their games that way, so they all feel the same?
I saw Millz Tron last night and it is amazing. I plan to go with LED's, pinbits protectors, arcade mod, light cycles. The priority for each is as listed with LED's being the most important. As other have said, protectors for the game would be a given. My game is routed so adding protection now simply covers some of the areas that have had miliage.
Welcome to the Tron club. I love it more than lamp.
