Dunlop nylon .60 (the light grey ones) out of choice. Occasionally a .73 on my OM if I feel like drowing everyone out.

I don't generally like heavy picks but have nevertheless been impressed with Japanese Kasho brand picks, several of which I got as samples.

Failing that, any pick I can retrieve from that discontinuum in space-time that seems to gobble most of mine up on a regular basis!

Peace
