These are larger than a standard Jazz III pick, almost the size of a standard 351 pick but just slightly smaller. The biggest difference between these and the nylon Jazz III XL picks (besides the material) is the edge geometry. These Tortex Jazz III XL's have a hard edge with no bevel, so they may be awkward to use until they are broken in slightly. This could have been helped if the picks were tumbled to take off some of the hard edge. You will notice the 90 degree edge factoring into the feel and playing more at gauges above 1.14mm. Overall this is still a good pick and great for a variety of styles of music, especially those that require playing single notes with speed and precision.
