Put a set on my TZ. I don't notice much of a difference in the bounce. But the difference in how it grips the ball is night and day.
So much better control and aim. I can now hit the slot machine scoop almost every time I aim for it now.
On my first game with the Super Bands installed, I got a 2.6 billion point game. My typical "good game" with standard rubbers is usually between 1.2-1.7 billion.
A HUGE thumbs up from me on gameplay and the way the translucent rings really make the playfield art stand out in a good way. I'll judge how durable they are at a later date.
