I have also used Dunlop pretty much exclusively. Playing acoustic, I used JD nylon anywhere between .60's or .73's for the longest time. (The grey nylon ones. Not sure if they had a name.) I then switched to Tortex .60's as I found it gave a significantly brighter sound.

After my long musical hiatus, I picked up the electric and quickly found I wanted a stiffer pick.

JeffS65 had previously posted about "plate sized picks" (lol!) so under that influence I picked up a couple of JD Stubbies (1mm). I like those, too, but I still like having the dinner plate if my pick gets twisted around. Gives me something to push it back to correct position. I guess I feel I have better control of it.

After giving the Stubbies a fair go, I have been migrating back to the Tortex.
