I have Superbands flippers on all my games! Love them and they are very durable and clean up super easy! I've had them on MET since I took it out of the box (in June 2013), and they still look and play great. Been to lots of shows and no signs of wear and clean up is a breeze!
I also have Superband rings on several of my games...MET is completely converted to Superrings and same thing no wear and clean up super easy. Here is a post from a Superbands thread of one particular ring on MET that I had replaced several times due to wearing through...since I replaced it with the Superband ring it has not shown any wear. (my post is #6)
