Here are the results, the LI on a 07 z06 JTG front and rear from 1000 feet under,(thats all we had). M45 on 06 viper, JTG with PL3 and a couple of PTs with the 20/20. (the driver would have had plenty of time to slow. the 00 viper with SR7 was the same as the viper. JTG on the PL3 and a couple of PTs on the 20/20 with plenty of warning.
