personal think this map is kinda overmap , cuz you add quad at 00:09:017 - 00:10:017 - ..... (each white line ), although to some extent it is reasonable , but i think there wasn't a very loud sound to add quad , second reason , if you do this , you will ignore some finishsound like 00:12:017 - 00:28:017 - 00:29:017 - 00:30:017 - 00:31:017 -
so i think double will be better, and keep quad for cymbal.
