Guys, probably only of interest to noobs, but when I stripped my demo man p/f I also rebuilt the flippers. Old weren't too bad - very minor mushrooming but also some movement - definite improvement with the new ones in. It's a surprisingly easy job (with a rebuild kit) - it was 10 mins per side for me without experience. What's interesting is how much better designed the new parts are for tightening the flipper bats - the old parts had a std nut one side & an allen nut the other - NIGHTMARE to undo & to tighten. The new part has one side welded fixed - so just one std nut. So easy to tighten & get flipper properly aligned. Pic of old/ new below.
