I know this is a "gear accessories" question, but I think it borders on a technique question so I hope this isn't too out of line in this forum. I'm trying to break my addiction to Dunlop 3.0 mm Stubbies... what I thought was a technique/tone problem turned out to be the chirpiness of the hard Lexan picks. I switched to Jazz IIIs and suddenly realize that I can split my Jazz IIIs into two distinct piles; some are clear-sounding and very controllable (both feel and sound), while others feel less "sure" and sound a little fizzy (sorry, the best I can describe it). I thought it was in my head, so I marked the "fizzy" ones with a marker, threw them in a pile, tried each without looking, and threw them in separate piles again... got every one, 4 fizzy ones and 5 good ones. Did Dunlop change the materials or something? If so, the "good ones" are hopefully what I'd get today (I've bought these over the course of many years). Or am I just making myself crazy?
