Quoted from Nokoro:If you look at my post above, there is really no choice with Star Trek. The standard rubbers shred almost immediately, and they are even more of a pain to swap out due to the inaccessible locations they are in. You don't want to be doing that every 100 games.
This is an issue with the rubber that Stern gets, which I believe is PBL (not confirmed). I have pulled odd post rubbers that were likely original from 80s and 90s games, that while they were not very nice looking anymore, still were intact.
The only mini post rubbers I have ever had go bad in my years are the PBL ones, mostly for the mini posts and flipper rubber tips. Ones from PBR, the Wico, still look new, other than maybe needing a cleaning here and there.
