Ended up with the Deda 38cm Big Piega Bar - its narrower as Deda measures from outside to outside... and although i was kinda wary to make such a drastic fit change it was a GREAT idea to stick with the "handlebars as wide as shoulders" adage. My arms fall so comfortably and it gets me into a more aero position in terms of width. I thought there might be a loss of control, but in this department the change is negligible... in fact the lining up with my shoulders just overall feels "right" and I need more time to say for sure but right now I miss nothing about my 42cm (center to center) bars.
