Very popular bike here in the hybrid forum. A lot of us ride hybrids because we prefer flat bars. Flat bars are not necessarily going to slow you down that much. If you set it up so your back is more horizontal than vertical, you will be in a roadie posture. Long barends and/or aerobars can be added to allow more areo alternative positions.
If you prefer drop bars though, a cross bike might suit you better if you can find one. Local dealer will order one for you...
