True Hoops from DW are a technology developed out of a multi-year-long project to improve on standard triple-flanged hoops. These hoops, which have a fully-rounded outer edge, hug the bearing edge very evenly, and is designed specifically to help both the drum head and the shell vibrate freely.
This snare-side counterhoop will keep your bottom head tuned evenly all the way across the surface of the head and help make clearing/tuning your bottom head easier and more stable.
