Just recently moved away from the Dunlop Ultex 0.60 mm because they kept breaking on me and or have sharp corners/chips develop too often. I went to the .72mm's, which seemed to have fewer issues with chipping and defectively cut corners from the factory, but I just wasn't vibing with them. I decided to take a gamble on the Dunlop Jazz III (Tortex) XL's... I grabbed some 0.88mm picks and really enjoy them, I think I may order some 0.72mm's sometime soon! I found the regular Jazz III's to be great for fast/precise playing but felt they had limited 'range' and required a lot more wrist-action when transitioning from string to string, which was too fatiguing. The Jazz III XL's are perfect for me because they have the Jazz III shape but are larger in size, yet still smaller than standard-sized picks. Definitely recommend trying some if you're interested in something new between your fingers!
