I have kit #2 installed and we tested two different runs of Pinball Inc. Ramps on my game. They pretty much broke every time we touched them. It's thin wire, it's just the nature of the beast. I put the expansion kit on my game as well. There are parts of that install that are tricky to say the least. It's cool, but it almost looks too stock and only AFM owners might notice what it's doing. Both kits are awesome though!
