On the subject of climbing ethics, no-one else seems to dig the mental flash. A lot of times I get to a crag, and I look up at some route or other, and I can just see it; yep twist foot in there, crank with the right, pull up, rest, etc etc, and it all just flows and slots right in until you see where to get to clip the anchor. Done! Mental flash. Usually, if I get one of those I just move on and get on a different route. What would be the point of doing the one I’d mentally flashed? You should be able to log those somewhere. Not everyone can mentally flash stuff. It takes a lot of experience and even nerve, because when you’re mentally trying a flash, you really are right there in it.
