Still debating on whether to purchase a Redline or V1. The V1s decreased sensitivity vs the Redline against Ka 35.5 concerns me as well as the Redline slow response against I/O and Q/T. Although, I'm wondering if the V1 may be hindered against I/O and Q/T with Ka Gaurd on. Terrain is relatively flat here, but roads and interstates tend to have many bends and curves and also trees dividing the median in certain areas. Therefore, off-axis detection may not be as much as a necessity as someone driving in very hilly or mountainous areas; although, it is still somewhat a necessity since my area isn't exactly like the flat plains of Kansas or Nebraska.
