I play bass with a pick, lots of chords and hard strumming. These picks are perfect for me, other picks might crack or simply wear out after one rehearsal (or one very intense song) but these last me a good while longer. I think it has to do with the slight flexibility they have, even though they are very firm. The coating wears off after a few hours of use but if you grab a new one when you go on stage you will have extra great grip through the show.
