Do it with a ship cap of appropriate mark triangles in the mix for both sides would be a better sim. Simming a ship cap of MRLS 1 vs a ship cap of Tachyon Microfighters doesn't tell you as much as a ship cap of mk 1 triangles + ship cap of MRLS vs a ship cap of mk 1 triangles + a ship cap of microfighter mk1s. That is still very very rough though, and actually trying it in game with omega devices and stuff to rush the economy section of the game to test the combat by itself is even better.
