I read through most of the thread on this and watched the BRS video on the Flipper. I'm leaning towards a Flipper but not sure which one. Our 180 is 1/2 inch glass. The middle one says up to 1/2" and the Max up to 1". I was thinking maybe get the Max in case I want to put a microfiber towel between the dry side and glass. I'd rather pay the extra than end up regretting not getting the larger but don't want to get a workout using it either. Any experience or thoughts ?
