"With unpaid amateurs one shouldn`t expect too much. As pointed out before they do it for their own enjoyment, so we should let that go to a certain extent."

Know what? This is a very patronising attitude. That aside, I've found, in my fairly wide experience that I've preferred amateurs of the pros simply because the amateurs are playing because they love to play, and, therefore, tend to experiment more, which in some cases drives traddies crazy, but heh, such is life.

Smile once in awhile, it'll do you good!
