You can go bankrupt in radioactives early in the game with double warhead small mines. I am building single warhead small - see TDM-Modpack politics in really big game. Later when I have a higher yard rate and excess rads I will build double warhead small. I think larger mines make no sense until minesweepers do different rates based on size. If you expect the entire field to be swept, park a fleet of fighters on the minefield. If you can afford it, put bases on the field - lower maintenance than ships. If you are throwing away surplus, put a fleet of dreadnoughts on every minefield. Then when the field is swept, skip replacing it.

P.S. When you are near the limit on units in space it makes more sense to use large satellites to defend warp points. They get that first shot before ships can move out of range. Be sure to put the best shield on them or they will die like flies.
