Well I finally had a chance to test my setup, thanks to forum members DJrams80, and RacerX. Both of these guys went out of there way to help out by providing the laser guns and testing expertise.
For those that haven't seen my setup, it is in this thread: http://www.radardetector.net/forums/...-complete.html
In short the LI's are phenomenal jammers. The front was JTG against all guns, and only the Stalker could get consistent PT on the rear. The PLII got a couple PTís on the outside corners of my taillights, but was JFG with rear CM shots. We tested with PLII, PLIII, Laser Atlanta, 20-20, and the Stalker gun.
The 'OL Heap has lived up to the name I gave it, "Grey Ghost".
