Anyone running flat top bullhorns and are they comfortable? I know the idea is being able to mount base bars but was wondering if they function sort of like Ergon grips by distributing pressure over larger area if you are grabbing the horns with your palms resting on the flats right in the corner. Can you actually ride the flat area near the stem or is it awkward?

Cinelli Mash's look a bit extreme and expensive but know there are some others out there.
