I used to use Dava Controls, then V-Picks Screamers and Gravity Picks Stealths that were 3mm and 4mm. Then I got hooked on Dragon Picks. My main is 6.7mm while the others are 6mm or so. Unfortunately the guy that made them passed away. He seem to be a pretty nice guy had some really cool designs. I have yet to find another pick maker for future picks.
