i have the easton ea70 wing bars...i love having the flat top...sooo comfy..it's nice for the long climbs so you are forced not to squeezed the bar...also, i found that on long straight aways i like to get into a "tt" postition by resting my forearms on the flat tops of my bars...i couldnt imagine doing this for long with rounded bars...the flat section spreads out the pressure when im down in that position
