If you do some more searching around, especially on the radar detector forums, you will get a far better idea of what radar threats are in your area. Plus, the more time you drive with your V1, along with the time you spent with your Passport, will give you more confidence on what threats you should or should not worry about.
I've gotten to know my area/routes pretty well, and I won't be turning the K-Band off on my V1 any time soon. This is just my .02 cents from down here, and hopefully some SF guys can chime in with better info.
