I've tried all three kinds extensively over the past years, compared (rubber, silicone, eurethane).
I now only replace rubber parts on my machines with eurethane. Partly because they last indefinately, but also (to me) they play better as well as being cleaner for the machine.
Rubber is high maintenance with crap residue gunge being spread all through your game. Silicone is weak and prone to wear, tearing, premature failure. They are not durable like eurethane. I don't mind the way rubber or silicone plays, don't see that much difference than eurethane at all really. Eurethane turned ot the best value for money by alot.
A few thousand plays down and my TNA silicone is about done. Shabby, frayed, and distorted. They will soon all be getting replaced with eurethane.
Not a big deal. Just the way things ended up from my trying stuff out, and economics. If I noticed that eurethane played really badly or noticably more difficult, then I wouldn't be using it.
There's nothing worse than tearing a complex game down to the playfield to replace rubbers, then a POS silicone rubber tears/snaps merely months later leaving you to tear the game down again. Silicone by nature is prone to tearing if there is Any defect or nick. Yet I have "defective" eurethane bands (air bubble inside) that are still the same condition as the day I installed them in 2018. Silicone simply puts me at risk of a whole lot more uneccesary work.
I will buy rubber if I must, but will never buy "silicone" for pinball bands again. Imho the material is kind of unsuitable for the purpose. Speaking as a fitter and machinist, and pinball tech.
I am grateful to spooky for putting something Cleaner than rubber on my TNA. A local guy, a mate, got himself a NIB Deadpool LE last year. That mob are so tight; among other shortcomings the thing came fitted with cheap dirty old black rubber. On an LE!? WTF?? .. Cmon Sterd.
