Quoted from CaptainNeo:Why would you take out all the inserts? I would not advise anyone to do this ever, unless the insert is loose and falling out already. It's very hard to get inserts out without putting micro fractures in them. Many inserts are impossible to find. So it's a very drastic measure. I've seen playfields ruined, because someone felt the unnessesary need to pull the inserts when they didn't have to.
His reasoning is they were all cracked...
