What I have heard is that the PF protector needs the playfield to be previously stripped before installing it, so is not easy to remove once installed. So If you go ahead and get one, It w¡ll be there for ever, unless you want to spend hours working with your pinball.
Apart from that I'm concerned about the possibility of that stuff slowing or interfering the ball rolling in some way so I ordered mine without that feature for now. With the cliffys and the required mylar protectors in critical areas you should be all good for a HUO pinball, and also save $150 in an allready very expensive toy.
