GNR was one of the first pins I bought, I chose it over a TOTAN for the same price, same condition. The whole package is unparalleled, it stood alone for nearly 2 decades as the only real "rock" pin until ACDC and MET came along, and like MET it is a Borg design with Lyman's participation as well. It is the only game with 3 mid-field magnets slinging 2-to-6 ball multiball every which way.

I've gone thorough a round of trying to brighten up the game, being 20 years old... really hesitant to go LED which would affect the light show. I'm not yet convinced this game is a good candidate for LEDs, but I think it can be done somehow.

On mine the hinges of the G-ramp door touch the wireframe below, so after it opens it gets stuck in the up position. It sounds like yours is doing that but to a lesser degree. My fix is to put in a spacer to lift the G-ramp just enough so the trap door has plenty of clearance to go back down without resistance. I have a replacement ramp that I hope will resolve the issue, just haven't got around to installing it.

Nothing a little duct tape won't fix

Good News!

Sounds like a good option to replace a damaged original, not sure I'm seeing it as a compelling upgrade.

That is expected behavior with most dual flippers. Some of the tutorials I've seen show how you can cradle a ball with the lower and still use the upper, so it's actually a nice feature.

Pics make a good guideline but I have yet to see scheme for this game that I like, so even though I tend to use mostly colored bulbs, for this one I'm leaning toward mostly white... just making it brighter than stock goes a long way.

Sounds like some flipper tuning is in order. Clean all the grease and replace the coil sleeve. If that doesn't work consider a flipper rebuild kit.
