anyway, regarding the neck pup positions, we must remember that it is relative to the fret you're on. When you play up the fretboard, the neck pup's position changes. When you're say on the 22nd fret, the neck pup is in the same position as the bridge pickup.
Personally, i'd would choose the number of frets over the neck pup position, cuz afterall it does not affect the guitar's tone in the same way throughout.
