Do we need larger mines than small?

[geoschmo]

The only time a small mine is better than a big one, is if the enemy can't sweep 100 mines, but they can sweep some mines and you don't have time to get enough large mines built to get past his sweeping capability. So unless the enemy is bearing down on your planet two turns away and you need something, anything, up right now, go with bigger mines. Any time you are building defenses in preparation for an assault that is not in the actual act of happening right now, go with big mines if you are going to use mines at all.
