Picks are a pretty personal thing and I seem to use quite a few differnt types depending on the job in hand, but Dunlop Standards are the mark by which all others are judged. I have a whole load of Standards in different guages for different sounds, styles and guitars. Size, shape and grip on all Standards is good , and these 0.60s work well for me when hybrid picking on acoustic.
Like all lightish picks, they can go a bit blunt and/or furry over time (but not so quick it's a problem) so it makes sense to get the multipacks
