In New Jersey all bands are used I run my R7 and R3 30% on X and 40% on K 100% KA & Laser. Works well very few faults and still get enough time to slow down.I'd like to comment here that, per my testing, if you see K or I/O K, it may not be a huge detriment to just run K at 50% or so if you live in an area with terrain that provides frequent, major choke points to detection, like sharp curves and elevation changes (hills). You may not get an inch more range on 100% vs 50%, but you'll certainly be less annoyed by BSMs. Just a thought. Use your best judgement.
