Basically, for the type of music I play, the HDs are too tight maybe, too clinical. Everyone told me that I'd do well to have a pair of Mules of VHIIs in my PRS and they were probably right. That'll cover the vast majority of tones I need. I just wanted the output for the sake of it really.
Maybe you are right. Maybe the RYs will also be too hot. Maybe the sensible thing to do to is to buy Mules. I generally play Motley, Slash, Halen, that sort of thing. The HDs are really aimed at the more metal player I think.
