Dunlop 44P100 1.0mm Nylon Standard Guitar... -- yes, as one who changes Picks for tone and feel, this is a cross between wood, and bone or antler as I use it. I use the Round Corner and at an angle and seek a softer chime with some attack. And the thickness is purely for grip for me and only somewhat effects tone in how I use it. Thinner would give more attack, --with how "i" strum.
