My understanding is that among the benefits/characteristics of round-over bearing edges is that more of the edge is in contact with the drum head, which tends to dampen the drum head slightly and which engages more of the tone of the shell in the overall sound of the drum. In light of that, how would a flat bearing edge sound? Have any of you tried that with one of your drums, or played a drum with a flat bearing edge? Any personal experiences or opinions are appreciated. Please, no bickering or disparaging comments. Thanks!
