I used a very old Jazz III for years. It was pretty worn out, so it had a different attack and feel, which I liked. After I lost it, I looked for something with a similar shape and thickness but with the right amount of roundness. I think this one has a perfect balance. The material feels amazing too. If you are used to smaller picks and prefer a slightly rounded edge, you should try this one out. I tried many Primetone picks of different shapes and thicknesses, but I find this one much better. I just wish Hense made more picks around this thickness (instead of bunches of 2mm models).
