A triple fits your needs. Maybe it fits others needs as well. Sure a double can be used for touring. Why don't you change over and see how well it works for you? To so vehemently support doubles and castigate triples as just as vehemently is disingenuous if you don't use one yourself.

I suggest that people use triples for the same reasons that you use one...because it will probably fit their needs as well. It might be best to start with a triple and remove the inner ring if a tourist finds they don't need it. But, generally, it's better to have it and not need it than need it and not have it.
