So Ka detection on the V1 .872 sucks. Especially forward facing Ka. Love the V1 for other bands and for its superb I/O QT detection. However, I feel myself wanting more in the form of Ka detection. From all the vids I've seen the Redline and V1 are pretty close when it comes to picking up Ka radar that is faced TOWARDS you. However, forward facing, it seems the Redline is much better than the V1. Can you all confirm this? My question is this. Is the STI-r PLUS worth the extra money, when all I want is better Ka detection? I don't care about GPS, Red Light cams, or any of that other stuff. Just want better Ka detection. Should I go with Redline or STI-r PLUS. Is the STI-r THAT much better?
