I have two Ebony necks, two Wenge necks, Two Pau Ferro necks, and a Bocote neck. They are all dandy. They have their own personalities, but all in all the all are pretty good sounding. I have also become pretty devoted to Roadhouse pickups, they have mojo. I still want to try a Goncalo, Rosewood, and a Canary neck. I have projects for most of them, just not the disposable income. So far my favorite necks are the Wenge ones. It is not for everyone, but for me, they have a nice amount of mid push to cut, and are wicked slick to play. Can't get enough. I have also gone over to the '59 round back profile. I love the Standard thin, it is very close to my main guitar growing up, but that 59 is just a bit comfier. Never had trouble with the necks getting mucked up with hand grime, and I tend to have sweaty hands. Oh yeah, get the stainless frets. For no other reason than durability. You'll probably find other reasons to like them, but the durability factor is off the charts. Good luck with choosing.
