I'd love to see roasted necks as an option on all models going forward, both finished (a la BFR models) and unfinished (like mine!).
I have one of each.
I buff out the finished neck with guitar polish and it stays pretty smooth. The more I use it the smoother it gets.
The unfinished neck is the smoothest (like silk) of all my basses and given a choice I would go with that.
