I hear you and that is a good point.
Another way to look at it is that perhaps canopy work is to the place now that it should stand on its own and be its own product and its own discipline that others can use and modify to their liking. I'm not saying "break away" but it just seems to me, coming into these things late in the game, that the two disciplines have become very different and perhaps it is time to address them as such, very different. In fact if anything the association just adds to the confusion.
This of course is from my perspective, not having done much rock climbing and being introduced to all of this when it seems so "mixed-up" but different. The more I think about it, rock climbing seems more different than similar to canopy work.
