I have been a long time V1 enthusiast but recently i have acquired a STI-R from Micah "blinder-Guy" which was a good experience. I will be running this in combination with my v1 to keep the arrows with the v1 high and sti-r low on the bumper. It will have a unobstructed view. I will keep you guys updated on the performance, falsing, and other issues which may arise. It just came back from beltronics and will mount it up soon it has the newest firmware with the audio ramp up.
