I use the Dava grip picks https://www.davapick.com/griptips .

A number of lead player I know use these tiny, very hard picks. My fingers are so big that I have trouble keeping ahold of them.  The Dava grips are easy to hold - no slipping. Also, you can get a different feel depending on how close you grip the pick to the tip. Choke up on the tip and you get a firm, tight response, grip a bit further back and you get a bit more flex.

Hope that helps.
