I usually dont bother with RW and SW unless im on a 200+ galaxy with hard AIs and encountering problems - which really doesnt happen anymore - as said they come to late in the game - yu can mod that tech tree so the stellar manip is easier or lower Sw and RW to level 1 tech and halve the cost of the components and plating etc. That way its in the game early on and the AI does attempt to build em. But in a standard stock game it just comes to late - now maybe if we had a 500 system game it might be useful with a hard smart AI.
