I have weirdly shaped ergonomic bars, in a 42 I think (I must look like a linebacker). They're more comfortable in the drops, but the brakes are a little harder to reach... I have to really jam my hand into a little indentation in the bar to get good brake action on serious downhills. My bike shop wasn't very sympathetic and I've learned to live with it, but I know you've got a better relationship with the boys at your LBS, so they can probably help. But back to the ergonomic bar, if you spend any time in the drops it does give you multiple hand positions, so they are more comfortable.
