Redsnail: Thanks for the response, I had not thought about that aspect re: WX. (although I'm meeting more CB's at FL390 than I would like). I remember getting good advice from you when I didn't even have a PPL so people should listen to you. Many thanks in retrospect.
Lord Lardy: An interesting response, I naively thought that a TP would be easier. Live and learn.
All the best.
