I was going to run the line such that it would be supported at 12" intervals, but at this point it is a simple matter to turn some tabs around so that it runs right next to one of the strongest tubes in the airplane and I can make the tie-offs much closer. The next question is "steel or aluminum brake/fuel fittings?". The steel is obviously stronger, but wouldn't there be an increased risk of dissimilar metal corrosion? -- This is by far the hardest lesson about freedom. It goes against instinct, and morality, to just sit back and watch people make mistakes. We want to help them, which means control them and their decisions, but in doing so we actually hurt them (and ourselves)."
