Reaction times have no effect on ET, but your 2.4 60ft does. If you could've dropped that to say a 2.0 or below, you definitely would've been able to run low to mid 13's. Worn out RFT's would be the culprit for this, but good runs regardless. I'm thinking when it cools down here in South Florida, I'll be taking mine to the strip to see how it does.
