I want to do some drawing with my Cougar, and wonder which pens people recommend as being best for this. I would like to use something that has a relatively fine line, and is waterproof and light fast once dry. For my Zentangle drawings I use either a Kuretake Zig Millennium or a Faber Castell Pitt Artist Pen - would either of these be suitable, or would the action of the machine damage the tips?
