Currently using Jim Dunlop .73mm grey nylon picks mainly for electric and acoustic guitar, and occasionally on bass but working harder on using fingers at present. When playing bass several nights a week about 30 years ago Jim Dunlop 1.0mm black nylon picks were the go as they are durable, did not give off an obvious pick sound, and not so hard that you would end up breaking strings, as did happen on a few occasions using the typical hard plastic ones. If you want more bite or attacking sound from picking would suggest giving one of these acrylic ones a try over metal ones.
