Gum - gelatin sizing or not?

Hi all,

Just a quick check in with you more experienced folk. I have heard
mixed opinions on gelatin sizing for gum. Curious to hear your
opinions, or is the need more related to paper choice or pigment
choice? Or does the size of the finished print have a role as well?

Thanks a ton for your input,
Dwayne
