@Fatcapp. Have re-tested percieved suckability of both Rose and Hadalay. Think that the Hadalay is actually just a wee bit more open in retrospect but not much in it really. A Kennedy, for example is waaaaaaaay more open than either and a Kabuki way tighter. I needs me one of them Nitecore suckometers for a more accurate assesment but them's my feelings
