I play plasticovers. #3 on a .110 opening, custom Link STM, Runyon Quantum (metal and delrin) HR Berg… I have played fibracells and found them similar to V16s in response, but tougher on my chops (when I wasn’t playing as much) Tried some ZZs, but not used them enough to really rate them. I’ve played Bari, Bari*, in both tenor and baritone (on a tenor mpc) but they wore me out and sounded more “plasticy”. I’ve stuck with the Plasticover’s for years.
