Problem here is that nobody really knows anymore what the OD Inter-17 (F17) specs are ?!
There been so many of them and the class rules almost explicetly state that everything as delivered d by PC or their dealors is OD compliant. But that is a topic for another forum.
I'm sorry to hear BC coming down with significant damage, never a good thing especially if caused by another.
