UK - we operated 2 twin squirrels on powerline ops and had to send the bits away to Canada for fixing/servicing because we would have a ship on the ground for months otherwise - and we were doing 5 hours per day on 4 machines. Totally unacceptable. We also had 2 206s which were much more predictable in terms of operating costs and servicing.
The only real advantage a B2 has over an LR is you can get an 8 foot pole across the cabin
