You killer is your 60ft time. Reaction time doesn't effect your ET or 60ft, you could have sat there 10 seconds and your et would be the same as it would if you cut a perfect light. If you want to try and shave 10th off your time try shallow staging, where you barley trip the bulb you will get more rollout before tripping the beam and have a little better 60ft time and get you in the 12's..
