I purchased one of these for my first pin. I played the machine about 10-20 times, then fully shopped it and replaced all rubber and installed the protector. That is important to understand as I ask my question. Has anyone noticed that these greatly increase the ball's ability to "grip" the playfield and spin. Seeing as I replayed all of the rubber, flippers, balls etc. and this is my first machine, this could be completely normal with new parts.
