I give it a 5 only because I really like the grip on the Dunlop picks.  There's absolutely nothing wrong with these picks.  Having said that, the .38mm pick is really, really, really thin.  Although I needed a thin pick for some accompaniment work on the acoustic guitar, these picks barely makes a whisper.  I'd have been happier with something a little stiffer.  They're not really meant for picking out melodies.  There's almost no feel to the pick on the string.
