I will watch this thread with great intrest. I just got a WW for myself and it is one of my alltime favourites. Fortunately mine only needs some cab touchups, decals around the spinners and a good strip and polish, also has the factory mylar 
I will be adding Pinball Pro speaker kit as I think this pin really benifits from the big sound of their full kit and also I'll use full LEDs. Tossing up whether to strip the mylar. Perfect timing for this thread as I hope to get some tips from the expert 
Mylar stays on this title Gav. I'm really hesitant with mylar removal on SYS 11 games. Paint and insert lift are a real concern, and I learnt that polishing this factory mylar with the treasurecove kit gives fantastic results (Pinbot Restoration). I think the only major concern is the wear on the areas above the spinning disks. I have new decals for that, and I believe that there is a decal kit that can be applied to the surrounding artwork. I'll look into that as well.
I think you are right with leaving the mylar on. I'd shit myself if paint started peeling. I purchased the TreasureCove kit specifically for this pin as its my only one with the mylar. I got the decals for the artwork around the spinners from ebay. I'll be putting mine on wet.
