I understand where you are coming from-but there are times when wood is the only framing material available ;) . To a degree this comes across to me as boiler plate "We're not responsible"-though in my mind the only thing the speaker builder should be held responsible for is if the fly points hold or fail. The problem is that the language makes it difficult for me to always follow their instructions thus requiring some interpretation as to where to draw the line. (part of my day job responsibilities is overseeing hoists and rigging in an industrial facility-I do not consider myself an expert-but I do understand the issues involved safety factors and all that) One of my biggest concerns on this hang is that if one screw hook fails it comes down.
