Unfortunately Nimbus many people here only hear or read what they want to. I thought I wrote a reply to Finals 3 Greens but it has been ignored. You are clearly an experienced glider pilot and have made some very useful contributions to this discussion. I have found that having experience in other areas of flying is very useful in my main job as an airline pilot. Too many pilots have too narrow a view and that can compromise their flying safety. For example the lack of knowledge of some power pilots of what glider pilots can do in or out of cloud.
