Completely cloudy beer! One thing of future use for you though Tim. Nch would probably only have offered you a FIS (traffic dependent) because with the greatest of respect to the short-trousered one and the rest of the guys and gals they've got better things to do than talk to transit traffic when they're not the 'official' LARS provider. Colt would have been able to give you any kind of service you wanted, zone only sees a couple of north sea heli's an hour!
