Remo had great idea with PS 77 (I do like that number), but this is just hybrid of some existing drumheads (alomost like Powerstroke 4). Also, underlayer ring is glued to top drumhead and it makes precise tuning impossible. Maybe onkly with drumdial or Tunebot. Like Evans Hydraulic, this is thick and dull drumhead which can make happy only heavy hitters. Also, I find Remo has colder sound and not so good coating as others.
