I removed three pieces of mylar from my playfield, two half-moons in front of the slings and a third up the long cast chute. There was some bubbling and clouding and I thought it would look better without. Now that I've done it, it looks nice, but I'm considering whether for protection reasons I should replace with new mylar (including the full lower play field mylar from marco) or just leave it as it is for right now. I've seen some opinions that slingshot mylar is a good idea in all situations, and just wanted to see the general opinion of the site.

Thanks for the responses. I ended up leaving the mylar between the pop bumpers because it looked like there was a little wear up there and was afraid to remove it, and in any event, I doubt most people would notice it anyway because the view is mostly blocked by the ramps. I was amazed at the difference in build up on the playfield when I compared what was under the mylar to the rest, and this motivated me to really put a nice polish and wax on the rest of the playfield, and while I can still see a little bit of a line where the mylar was, it looks really nice and ultimately I think I'll be more happy with no mylar. Now if I can just get that ColorDMD
