I'm on the quest for better pick grip. Many of the picks I've tried have a very smooth surface, they sometimes slip out of my hand during hard playing. Some of the picks with built in grip (like textured surfaces) end up scraping against the strings. I also like thin picks, and smaller picks. The size doesn't matter much though as I can cut them down. So anyone got suggestions for a decent grippy material? Or maybe pick hacks? I may try a thumb pick at some point, have no idea how that'll feel.
