I bought these to try out as a replacement for the Dunlop delrin picks that I've been using happily for a number of years. The delrins were not very grippy and sometimes turned in my hand. These feel pretty much identical and I was surprised by how much more stable in the hand they were. Superb pick!
My only issue is that after ten years using very bright pink picks, these blue ones are harder to spot when you put them down :-)
Hey so yeah these picks are pretty good, the rough surface gives a better feeling to them vs smooth ones. They are jjust enough medium flexy for laying down them smooth strumming chords on your 59' strata that collects just the right amount of dust.
But all in all a nice pick, good grip, medium flexibility, and they're avarage durable which suits the most of needs.
