Dripping worked fairly well for us during the last freeze (Austin), although I still had a few frozen pipes (that did not result in a leak). The insulation is sufficiently poor that our indoor bathroom faucets will freeze after ~12 hours of <30 or so. There's pipes that run along the exterior of the home that have literally no insulation whatsoever. We'd have to do some targeted insulation in those exposed areas as well, unfortunately.
