A while ago I discovered these picks. I really liked them.
Then one evening I was reading an article about how picks effect the sound, and I took it with a pinch of salt. So I got a 1mm standard Dunlop nylon pick, and a 1mm one of these and tried them side by side. I was very surprised to hear that these were much brighter on the acoustic.
So the next day I went to my local store and bought a heap of picks all different thickness and material.
In the end... I came back to this as the best all rounder. Its not quite as bright and flappy as a celluloid pick, and much brighter than other nylon picks. BUT... the grip bit makes this best.
Its fantastic the way they have done these! Ya just don't drop them!... even when sweaty :) ... I just love them. Which is why I bought the big pack of them.
