Been looking into arena's and there construction recently, one of the main american arenas has dual layer polycarbonate up to waist level and single layer above. This arena is used for every weight class including SHW Spinners, but under UK rules the arena in question would only be rated as a Class 2. As a class two arena weapon types would be limited at heavyweight or above. This would exclude high powered spinners such as Last Rites and Super Megabyte which the USA builders accept.

So my question is would HW spinners be allowed if a UK arena was constructed in a similar way? I understand arena classification in the UK is based on the arenas weakest point, which would be the thinner upper poloycorbonate in this case which reduces it to a class 2 and limitations.

Maybe more of a point for the FRA than Jonno and RR. I'm sure insurance may pay a slight part in this but fully understand there may also be concerns about safety which I am not aware of.
