I have ran cca and ofc, same car same system. Only thing I switched was the wire. My score didn't change one bit. If your building a 100% comp car get ofc, if not then just use the cheaper stuff, as long as your not trying to get away with to little wire you will be fine.
Its not about your score. Its about feeding your equipment. If you use it to long it will heat up, heat = less current passing
