I just purchased a Mamba Hyperflux, and I have to say that this is the mouse of my dreams. I love it! It is ultra light, never needs charging, and it doesn't have a mouse cord to encumber me. However, I HATE the Firefly surfaces. The only options are a control cloth surface, or a control hard surface. I would pay to get an Acari or Megasoma surface replacement pad so that I could get something with more glide. Is this an option? Or, am I stuck using my NOIDpad (hybrid pad) on top of the Firefly?
