I bought these picks because i wanted to try something else besides my trusted nylon Jazz III XL.I play a lot of leads so i need something heavy.The pick is quite small,like the normal nylon Jazz III,made of tortex,meaning it has a mat surface.It's a heavy pick,nice for fast lines,but i felt that there is not much of dynamics,at least not as much as the nylon Jazz III.I felt it has a softer attack,which personally i don't like,and i don't like small picks.But that's just my opinion.All in all it's well made,nice grip,heavy but i prefer the nylon Jazz III XL because i feel i have more control and more dynamics.
