Thanks for all the feedback, especially the bar recommendations and illustrations of hand positions. I'm used to riding old style bars with aero and non-aero levers or with no hoods (fixed), so there's certainly a learning curve here about hand positioning. I find the noodles very comfortable on the ramps (shoulders) and in the drops. I'm going to compare the two set-ups a little further before swapping bars, but I also found the Zipp SL-70 Ergo (swept back, flared) and the Deda Zero 100 Shallow (deeper drop) which look promising.
