Fwiw the guitar I made had no radius on the fingerboard and I really like it.
Also I hold the guitar neck in the non-classical way, with my thumb round the neck, and not on the centre of the back of the neck.... most people that play like this seem to prefer radiused boards (judging by opinions I've read), but I guess I'm just odd.
BTW, dont be so pedantic perry
You know what he meant; string bends are used a hell of a lot in almost all styles of guitar playing, so a flatter fretboard will allow for a lower action, whilst still making bends playable. Sure there may not be a world of difference between a flat board and a 20" radius one, unless you do insane string bends, but theoretically, the action could still be lower on a flat board and allow for string bends.
Anyway, I'm sure you already know that
