Thanks very much for all your responses, very interesting. I have to say that Ive always payed more attention to the tafs and not really spent much time on the 215. From now on i will use the 215 more. Problem is if you are navigating in fairly tight airpsace like between luton and heathrow or between heathrow and gatwick, short of turning around and going back there arent many places to hide. Have to say Id rather not go than get stuck in one of those corridors and have to turn round as Id have spent quite a lot of money only to find that i couldnt do what i wanted to do. In a way Id prefer to save the money for a day when i know id be able to complete what i set out to do.
Thanks for your help chaps!
