I've had the neck for a few days, and I'm very impressed. Love the smell of roasted maple! It has a dark RW board that is just beautiful, 6100 SS frets that absolutely rock, and, yes, super light, which I definitely prefer over the modern construction.
I was going to sand it, but it feels plenty smooth to me, so I may just leave it as is. I did some slight finessing of the nut myself, and may take it in to have the edges rolled by someone who knows what they're doing.
Overall, mightily impressed!
