If you ever wanted to map the poles without distortion, then later make the map worlda, Equirectangular or some other projection; I have some good news for you. Using Gprojector, I've found a pretty easy way of mapping poles and the edges of the map with less distortion by using the projection "Equirectangular Oblique", and moving either pole you plan to draw to the center of the map (it helps having the lat/long lines with 45 degree intervals, this makes a large line around the pole). Simply draw what you want inside the line, then take that map through Gprojector (dont forget to remove the border Gprojector adds to the map, this will mess everything up if you dont!) and move it back to the pole with the previous method. It's probably best to combine images for the two poles so they dont get too distorted. You can also put the "Pacific" side of the map and move it to the center and edit it easily, but that's a given with Gprojector.
