As I mentioned two posts ago, I'm setting up a new tower. I just got thru setting up the preliminary defenses and the backup guns/combat pos modules (still need to get some hardeners and some ECM modules put down). Just so you can get an idea of how to avoid getting large quantities of your modules smart-bombed out of existence (thus making your attacker's job easier), every single module outside the shields is at least 20km from any other module.
Last night, we ended up in a nice high sec island in Derelik. Very calm and relaxing. Got to run the sites, got to anchor all these extra guns and get them loaded. The idea behind backup guns is that as the existing ones are shot out you simply online the extra ones. Or if your attackers only shoot at the online ones, you suddenly appear and online all the rest, dragging out the pain as much as possible.
I took this pic right after anchoring the last of the backup guns. After Wednesday's update I will pickup some spare hardeners and some ECM modules (and spares) and finish off the defenses. Then it'll be time to install all the industrial equipment (*shudder* - 10-30 min per module). I got the hybrid reactor and it's silos installed already. Soon I will be back in the T3 business.
