For the years I'm used to D'andrea pro-grip brites 1mm picks, but it seems that they stopped manufacturing it, so I looked for a replacement. I prefere Delrex picks, as they are something between Delrin and Tortex, where Delrin is hard, but slippy, and Tortex is opposite. Delrex is perfect working for me. These picks are very good, you can choose it in different gauges up to 1.21mm (I prefere 1mm blue ones). They are reliable and wear very slowly, so single pick is lasting for long. Also, price for 12pack is good. My full recommendation.
