Just before a mod pulled the plug on the recently-closed MMR troll thread, a good point was brought up:
Larry: "Same legs, same bolts, same levelers, same cabinet, and (lol), same tilt mech. All performed exactly as they did on a WMS MM. Levelers were fixed after a day and the games slid around on that carpet just fine."
Cody: "But are they the same legs? It seemed to me the Sterns ARE more "wobbly" because the legs are either thinner, softer metal or both. This was very apparent when I first got LotR and had a fresh experience to compare to all my other games. It was so prominent I was worried the legs might collapse. Really, they were that flexible. No BS."

To me, it seems that wobbly legs are caused by (worst to least worse): Stripped leg bolts, loose and run-out levelers (especially in front); loose OR run-out levelers, loose leg bolts, or the newer plastic cab protectors... maybe the metal ones but they seem solid. I don't know that I've ever seen a leg flex, but I do know the modern ones are lighter in weight than the old ones. Has anyone ever had to replace legs to reduce wobbliness on a particular game?
