I know I keep harping on about this but can someone from RoboChallenge make a verdict on saw blades please?
Myself and several others seem pretty keen on using them since they would be so fitting for the class and provided the Full Combat arena is used and people don't exceed the specs of the disks it should be safe.

Just want to know before I buy a load of parts and so others can get building.

The rules are a little ambiguous;

12.3 Rotating Weapons The speed of any rotating weapons - e.g. circular saws, carbon or steel cutting discs - must not exceed the manufacturer's specification. The manufacturer's specification must be available for inspection.
This implies you can use them with restrictions. Plus given the extreme nature of other spinning weapons it seems odd to oust circular saw blades.

Thanks (sorry for going on!)
