The first question I'd ask would be about reach - when you sit on the saddle, do your hands naturally fall to the hoods, or the ramps behind them? Do you feel like you have to reach out for the hoods, rather than that being the most natural place for your hands?
I have the same bar on my Bianchi, and what I find is the flat transition puts my wrists in a nice, neutral position, so I'm curious how you're bending your wrists. That, and when I'm on the hoods the neutral wrist allows my fingers to wrap around the hoods in a way that feels nice and secure, with one or two fingers on the brake lever.
