I would get the 13 Limited SL4 if you can get it at a steep discount. Raqball has it and he posted something like 16 pds and change which is very low in weight and will be super fast with the SL4 frame.
OTOH, you might really like the looks of internal wires and disc brakes of the 14 Sirrus Carbon Models. Those brakes are a luxury stopping on steep hills, no effort and you stop NOW.
