Cliffy is a good guy out in San Ramon, CA that builds out dozens of thinly milled metal pieces to protect badly worn areas of the playfield. His inventions add years no-wear life to high-traffic areas of the playfield. I have them on all my machines (where possible). I installed a Cliffy on my upper Black Knight ball lock, and it seems to be working as well or better than before. I am so thrilled every time a package comes from Cliffy. I know I am getting quality for my money.
