Yeah, the thread worried me too (especially because I have a Gibson with an odd looking neck - plays fine, but looks very odd when you sight it :lol: - so I'm watching the thread with interest).
However, I kind of reached the same conclusion - they're built for standard tuning, so why not leave them as that? If I slackened one off and then didn't play it for months, it could take days to reorganise itself when I do tune it back up...
I am finding with the new place (the old one was obviously an ice-box :lol:) that I'm going to have to go round adjusting a lot of truss-rods. They've all moved a bit, but they're all playable and I have higher priorities at the moment - so I'm leaving them "as is" for a bit. Give them all a bit of time to further figure out what they're up to!
