The Onyx and Black Suede are gonna give you a little more sustain. The Pins and Hydraulic, less sustain. I find the Hydraulics a little too muted, for my taste. Pinstripe are as far as I'll go, for muffled heads. So, it's really just personal choice, and what you want, sound wise. And personal experimentation is really the only way to go. Unfortunately, that gets costly. Maybe just order heads for say, the 13" tom. An Emperor ..... and a Pinstripe. See which one you like ...... and then from there, order a set to match. If you find the Emperor has too much sustain, you probably can cross the Onxy off your list too, then. If you think the Pinstripe is too muted, then you can retire the thought of the Hydraulics.
