I use Cartographer + Gathermate on my main. I have Herbalism on one slave, Mining on another and Engineering on a third. Only my engineering slave uses Gathermate because the Clouds are hard to see sometimes with a lot of herb and ore spawns in one place, so I enlarge them on his Minimap.

For the minimap, I use Chinchilla so I can have oversized and high-contrast Blips.
