Yea On my old fortress I had two GCS silk farms and a FB silk farm
Needless to say on each fortress I had legendary weavers continually pumping out masterwork socks trousers and vests.
I use the method for dropping silk down to the level below just cos I find it easier because every now and then I hit the lever 2 times and Im good to go for a while, If i dont I have to raise the bridge, unforbid the doors and tell the silk collectors to collect and then they sit around whilst the doors are fobidden and the silk is being spat. This method allows for a continuous stream of silk. I also like your idea of multiple lures, didnt think of that.
The only problem I have is that the dog gets hit by the occasional piece of falling silk from the bridges being retracted. This often damages lungs and hearts...
One huge advantage is, once these clothes start to wear out you can sell them and they sell for alot (especially CGS ones). I have had slightly worn masterwork GCS trousers sell for up to 1000 dwarfbux. I would trade 100000-200000 dwarfbux each year just to get rid of all my waste clothing
This current world I havn't found a single GCS
but on the upside I am about to breach hell and *hopefully* build in hell in like 5 minutes!!!
Should be
chaos fun!
-Edit-
It is complete. I have destroyed all the demons and an unlucky forgotten beast (a large shrimp?!) that happened to waltz into the demon slaughtering chamber. I am currently mining out the the adamantium and am beginning the new fortress. In hell.
