The guys at BD/moto fucked up the cables on my bike, with them being reversed so it was a new cable job. Place interrupters closer to the stem for more leverage since it looks like you have a wider bar. I removed mine because my handlebars were narrow. Might not be possible because the levers have a small diameter mount.
Your bars seem like its in a pretty relaxed position so I don't see how you're getting neck pains unless you're totally new to road bikes.
