Shaft help for AP2-714 Irons

I currently play the AP2-712 irons with Tour AD 65i Stiff flex shafts. My local Titleist rep doesn't have club fitting and it's not economically feasible to travel to one. Any suggestions on which shaft might be best?

Thanks Titleist. I received a phone call from Titleist directing me to a fitter that is closer. Thanks for taking the time!

UPDATE:  I ended up getting 4 and 5 iron in Dynamic Gold S300 because it has a lower penetrating flight. 6-9 Project-X PXI 5.5
