Well, I haven't heard any compelling testimonial in favor of a modern ergo type bar. So I'm pretty sure I'll just keep the bars I've got....

however if I was going to be nit picky I probably could use a wider bar, I'm fairly broad shouldered and I suspect that among other things a wider bar might help me open up the collar bones and roll my shoulders away form the neck a bit to prevent neck fatigue. I could also use a little more real estate around the stem for my bar bag,computer, compass & inline brake levers as well.

yah,, most of the curves, angles and dimentions to drop bars are just a matter of preferrence that vary person to person. as stated by others, the thing id worry about the most is width. most importantly on the flats of the bars. thats where you will spend most of your time so having that area about shoulder width will prevent arm fatigue and give the proper ammount of leverage.. to illustrate this. try doing a pushup with your hands touching in the center,, its hard,, now try one with your hands spread way out,, thats hard too.. the easiest pushup is with your arms parallel to or just a tad wider than your shoulders and thats also the best position for endurance riding.
