Speaking of the Classic, I have the 5 string version which became my main gigging bass for much of the '22 and '23 season and partly last year, too.
(The pics are for reference, used them in other threads here)
I hate neck dive and have a preference of thinner necks.
This Classic 5 has some of the beefier neck out of all my Spectors but to my biggest surprise it never became an issue (again, I gig this bass a lot so I would have noticed even after the honeymoon period)
The neck heaviness is noticable but I would not call it a neck dive ( the other picture is for how I hold the bass) and it never posed a problem.
Also it sounds massive (as all Spectors do π ) A little bit more precise, especially for slapping.
