I need some advice

Im getting a Giant OCR 2. Standard road bike drop bars.

I am toying with the idea of adding a second set of breaks on the middle part of the bars, you must know what im taking about, if not Ill try to post up a pic.

or I might swap out the drop bars for bulhorns and run ither a set of breaks on the ends or in the middle of the bars.

this bike is 90% going to be used for commuting, with trips maxing out a 2 hours.

Anyone have any thoughts/suggestions?
