Personally I prefer side B, but you are missing those three bands on the right of side A. if you don't wish to redistribute a modified/encoded file with new UVs, which is what they usually do, I can understand, as it's not necessary. instead, you can double the height of your texture map and then apply the dots as perfect circles, with the knowledge that the actual width and height of the map are immaterial, as the UV co-ordinates are only relative to the zero position in one corner of the template.
