Alfred, agreed, but CHF haven't done much at SL over the last 10 years. Remember, somewhere like the NAG with an OAT of +45 it's like starting at over 3500ft....the SK was, frankly, near useless in those conditions - the Mk4 Merlin will be better, but it still won't be a CH47 nor, maybe, a Mk2 Puma...
Of course, if CHF only hang around Norway then all will be well.
