I try not to wear all black, think it's one of the worst colours for being seen. As for the Gabba Ron, it's an expensive sweaty Jersey for winter or cool unsettled spring/ autumn days. Very aero but I think there are better options for breathability. I have a specialised Jersey that is similar, a bit thinner and for me better for fast winter training. Only problem is it's black so I only wear it on group rides.
