While I'm always game to try new stuff, I usually gravitate back to Ultex Jazz IIIs (427P). Love the shape and material, and at 1.38mm they're pretty much the ideal thickness for most of my pursuits. Good, crisp attack, without feeling like I'm wielding a doorstop. For certain rhythm-oriented stuff or where more flexibility is desired I still go through plenty of Tortex Jazz picks in .60, .73, & .88mm. Recently I've added Primetone Jazz III XLs in .88mm as well and have been quite pleased with them.
