I bought these picks because I thought they would be just like the regular Jazz III picks only made out of another material, I really enjoy playing with Jazz III picks and always loved the tortex grip so I thought it would be the perfect combination. When comparing to the regular Jazz III picks, the tortex ones have much more sharp edges, which makes the pick not slide so well on the strings like the regular Jazz III picks, this means you have to apply more pressure on the strings making the playing not so effortless. However after a week of playing the edges will get duller and the pick will slide much better on the strings, similar to the Jazz III picks.
They are very nice picks, i do like playing with them, however do not expect them to be just like the regular Jazz III picks but made out of a different material.
