For acoustics (most of my playing) I have been using the Ultex 1.0 triangular picks for a number of years.
For electrics I used to use Tortex .88 (green) for years but for the past few years I have been using Dunlop Primetone Standard 1.5’s. Like them a lot.
After many years I have found picks I really like and see no reason to change either. Neither are textured but seem to have great grip and don’t move around while playing.
I really don’t like the sound or feel of celluloid picks at all.
Grip can be "adjusted" with very coarse sandpaper and/or a drill with small drill bit for picks that are too slick.
