I love these for playing bass. They are thin enough to flex a little when you pick so the strings don't go out of tune. They are also slightly pointier than regular picks wich is great for metal and such. They are also slightly bigger than regular picks wich I really like for bass, perhaps because the string spacing means that less precision is required. I've used these on a few gigs and for recording, and they haven't made me dissapointed in any way. The grip stays good even after a lot of wear, so the only times I've dropped them, it was my fault. I would gladly recommend these to any bassist that wants a little extra out of their pick.
Sharp end gives these picks a tone characterized by sharp attack and lots of upper range. I've used .80mm tortex picks for a while and they last really really well. With a pack this size you're going to run out of picks for a while.
