An effective helmet is one that fits properly. Have an assistant use a measuring tape, or a piece of string to measure the circumference of your head starting at a point approximately one inch above the eyebrows in front, around a point in the back of the head that results in the largest possible measurement, and finally wrapping back to the front. It is a good idea to take several measurements to make sure you have the largest one.
