I just switched to a SK8er lid. More out of a sense of fashion. Have taken to wearing baggy shorts and t-shirts when riding. The old aero bike helmet was fine for Lycra and multi coloured jerseys but like the "urban" look of sk8er helmet. Had no problems with the heat but have not found a visor that would work for in rain. Am going through midlife crisis after having heart attack. Getting tatoo and dressing like a sk8er punk is my way of dealing with need to change life style.
