In general - do not like them!

Why... catches are a lot easier, often it is okay to just hold up your flipper. I also "feel", that they are more precise in shooting and it looks like they are adding power. Dead bounces are "shorter", so mostly they do not make sense anymore, even nudging does help much to make them "longer". Altogether is does not feel "original" anymore..

But - if it more fun to you playing with superbands... why not?

The original rubbers are an important part of the game... now other rubbers are coming up with "improved" characteristics. This can substantially change the way to play the game. Less skills are required to control the ball on the one hand and one the other hand certain skills are counterproductive... it is not only about "increased accuracy".

There are also other parameters that change the game... angle, outlane posts, new/old rubber, overall technical condition and many more - so it's not a drama, but still something to consider.

Personally - i tried them at home, I do not like them... but some friends of mine and me are running a "shared" basement, in which also our league is hosted. And there are superbands on some machines (but not on mine ). Everybody can do what he wants to...
