If your early in the game, you might want to get Small weapons out of the way. it's cheap, and would be a shame to waste a "free tech" from a ruins on something that only cost 5k reasearch.

If the ruins has small weapons, you will get nothing from it when colonizing the planet later. Ruins are seeded with techs when the map is created. Reloading the game and recolonizing gives the same techs. If you already have the tech the ruins are seeded with, you get nothing from them.
