The neck on my Special 5 seems stiff as can be. I assume that the ebony fingerboard can only be seen as a positive contribution to this
Don't know how much 'board's wood contributes to neck stability, but mine has an ebony 'board, too.
The neck on my Stingray Special HH also is straight as an arrow and seems pretty stiff as well. I've only had it for a few weeks, but the roasted necks on my SBMM Stingrays are also pretty solid. So no complaints here yet, knock on roasted wood.
Real straight neck is a good thing, unless it starts to back bow...and if the frets are perfectly leveled - and that's the case of mine (our, I bet!) 'Rays
