I used to run with a detector (Valentine One) but haven't for the last half dozen years or so. With all the "your speed" signs, security systems, adaptive radar, lane departure systems, etc., that trigger detectors they became virtually useless in urban settings and if instant on is used correctly, they will not prevent tickets. Yes, I know that some high end modern detectors mitigate those to a certain extent but not enough to make them 100% reliable. I sometimes wonder if getting pulled over, with a detector, diminishes your chance of just getting a warning.
I find that open highway speed limits (and the unofficial overage allowed) make for cruising in the 75-85 range (and higher where limits are 80-85) easily doable. Secondary roads still allow for decent speeds. The best defense I have found is not to do anything dangerous, keep your eyes open, if stopped be respectful, and don't speed in, or around, small towns where the local constable is acting as a revenue generator. Last time I was stopped was in Oregon ( my fault for not paying enough attention to just coming into town) which is pretty notorious for enforcement but was let go with a warning after a friendly chat. I actually had the guy laughing when my "friends" rode on by without stopping. "Friends of yours?" he asked. I replied "apparently not!"
