I fear this is a pointless discussion, or is there something big coming?
No body is going to build a class 1 arena unless it's for tv. There just isn't the money to do it and make it viable.

Spinners have been discussed to death and when we had them at wicksteed park most broke, and there wasn't really any damage.

The current level of robots would easy beat the spinners as it would take a fair few years to develop like has happened in the fw class before they became a problem.

I built ripper to fight not to play, I'm looking forward to fighting tiberious if it regularily comes to events now it's changed hands, it's something new to develop techniques to beat !!
