Do we need larger mines than small?

[Slick]

In general I agree, but I like throwing in a few turn's worth of small-1-warhead mines followed by a turn of "Big Berthas", then repeat. This way, if (for whatever reason) not all the mines are swept, the "Big Berthas" thrown in here and there will do significant damage.

BTW, if you are just interested in overloading the minesweepers, you can build really cheap small mines with NO warheads, then sprinkle in some with warheads occasionally. You really can build a lot of zero-warhead mines in 1 turn. Of course they can't knock out a half-dead mosquito if they hit...

Slick.
