The arena at Robots Live! cannot handle spinners of any description at the moment. Extreme Robots can but in the MW/HW categories, it is limited to 125mph. As far as HW spinner numbers go, I can think of Aftershock, Donald Thump, Tauron and Magnetar as being some of the big hitters at the moment but I don't think I've ever seen them all together at the same event.

If you really didn't want to face a spinner, you could mention it to the EOs at EXR but that might limit you to whiteboard/show matches only.
