I just got one of those integrated bar and stem handlebars, the FSA Plasma. The stem portion is square-ish and the bar tops are kinda wide and flat (more aero? debatable). This means it's hard to put on a regular computer or light mount because those usually use some kinda of round mounting clamp. I think I successfully got my computer mount on the stem portion, hopefully it's not loose and won't rub through the stem from road vibration. But now there's no more space to put on a little be seen headlight.

Anybody use the FSA Control Center accessory mount and like it? Is it pretty stable? How wide and how many things were you able to mount to it? Anybody use the one specifically made for the Plasma? I'm kinda not wanting to splurge the extra $25-30 but if it's awesome I'll get it...
