Intuition is defined as the act or facility of knowing or sensing without the use of rational processes. While their engineers tell me they know better, M&H still insists that their "Centripetal Tensional Resonator" is a crown retention device. If it works, there shouldn't be any flat (much less concave) M&H boards out there. There are. More chaff from the department of smoke and mirrors.
