Ebony is the best neck if you do a lot of bending. With stainless steel 6100 frets it's like rollerskating on ice. Almost like scallops. I oil the heck out of my rosewood necks to attempt to duplicate that feel. Pau Ferro needs even more oil but can work fine. Kinda looks cheap but it's fine. SRV seemed to like it. I don't mind maple as long as it doesn't have that thick candy coating on it. I like them when the finish starts to wear down and the thick clear coat won't allow that to happen. I've never heard a tonal difference in any of them so it's aesthetics and feel I care about.
