I doubt that PFA would have any trouble with an aerobatic capability - they have a reasonable selection of aerobatic machines on the fleet already. I'd certainly advise anybody restricted to PtF operations to go with them rather than CAA, just on grounds of user friendliness.
One question I've not seen any answer to yet is what will happen to the permissions for such an aircraft to fly night/IMC if suitably equipped if it is transferred from CofA to PtF without any change to the aircraft. Anybody know?
