I just realised I saw that game at Mark's the other day - and specifically commented on the playfield being nice for this game. They all bubble at the inserts, no real way to fix that (without removal and clearing!). Cab looked great too. Fantastic pick up. yes it's not a DMD but it's WPC nonetheless, and the alphanumeric use is excellent, lots of good info, makes you not notice it's not a DMD IMO.
The wear on the plastic above the kickout is normal as it rubs on the metal. If you aren't investing in a plastic protector set

As for the ramp, the issue is discussed here-

Let me know if you need any plastics - I have some spares and doubles of spares etc. Which sling plastic is broken?
