Ideal fretboard radius for a 6 string?

Tomorrow I plan to drive to Nordstrands' I'm Redlands to have my bass worked on. I have a wide necked Squire DJAV that I converted to a six stringer. It's got a 51mm neck at the nut, 15 mm string spacing at bridge.

I am not crazy about the standard 12" radius. I don't like the way the outer strings want to slide off the fretboard when played fast & aggressively. I think the radius seems to make an already wide neck seem even wider. I don't like the way that the fretboard (raised at the center) makes one have to arch ones wrist to gain access to the lower e and b strings. And my pinky (being so much shorter) is a little late on arrival on those low strings (when say, doing triplet arpeggio sweeps when doing walking bass lines). In short, the radius seems to slow down my technique.

I will certainly make the change radical, at least to a 20" radius, definitely not a 16" radius, & not a 20" compound radius--with the high strings elevated & the low strings further out of reach.

I am even considering a flat surface--like a classic guitar--no radius. It seems right, it seems I would get easiest access to all the notes. Segovia, Parkening, de Lucia, none of them had curved fretboards made. (My first instrument was classic guitar, nut I didn't practice at all.) Flat being ergonomically optimal seems logical.

I am inclined to think that a bass guitar's radius is almost a symbolic reference to a contrabass' curved neck-which is necessary for bowing purposes. If your play upright, you're probably used to the curve & crave it.

Recently a friend told me that his Telecaster's neck was rounder than his Stratocaster's & he wasn't happy with that.

Before making my decision to go 20" or flat, maybe I should seek advise. I don't have the luxury of trying both out first. I might regret either decision
 
I have a 5 string bass (custom made) with a flat (no radius) fretboard (the one in the avatar). I can achieve a very low string action, the strings height at the pickups is even and very comfy. Since the pickup covers are also flat they serve like a ramp. I've been playing basses with radiused fretboards for 30 plus years, and can't feel the difference when playing the custom. I think you'll like the flat fretboard.
 
I'm not sure what you mean by the pick up covers serving as a ramp. Do you mean to get a mwaah like fretless sound?

I put the project on hold, but I think I will go flat. The radius makes little sense.
 
Hi.. If you look at your hand at rest, without doing any force, you can see the fingers are not straight but at a slight curve.. that is the reason for radi on fretboards... most people find them more natural. However, many people find flat ones suit them better. It is just a matter of choice, no good or bad here.
