I used to play regular jazz 3's, they're feel thick, accurate and articulative.
After trying these out I couldn't go back to the smaller ones, I realized I had grown a bit since I started playing 10 years ago :D
These give you a bit more to hold and they can wear down more before they become too small or dull to use, and then you can always sharpen them against a carpet!
Great, moderately chunky picks, do recommend!
