McCoy, I always appreciate a good opposing argument. This is more about staying alive that whose e-penis is the biggest.
You make a valid point and reading through your response made me realize that I have in fact thought about the same when seeing people doing things and having strong opinions that differ whilst meeting them at crags.
However I do feel there is a point to be made for picking up a new hobby. I have more hobbies than arguments, judging by the equipment I have. Some of them I did once and although enjoyed it, didn't really get into it into the long run. In retrospect, I could have saved up some money on courses which would now be the source of funds for a trad rack (and a course

).
So ye, I am all for a course, but perhaps give it a shot first and stick with the ones that managed to not die yet, and when the hobby sticks, go get a course done. Having climbed for a while now myself, and experiencing different arguments, I myself are considering an official course to substantiate or amend my own thnking. As you said, super safe is best.
