Personally, I'm a fan of FZ utilization. Once a system for automation is set up properly, time involvement instantly becomes moot, barring running low and shortcutting some supplies accordingly. Pain in the tail or not, mixing in AE, Routers, and now Logi Pipes again, the FZ system is good stuff. It's fine solo, but like any mod in the pack, cherry pick for the features you want. Routers accomplish some things NO OTHER MOD CAN DO and should not be discounted. Wrath lamps are just convenience.
And with all this talk of FZ, I have to ask.
What the heck is the Leyden Jar about?
Admittedly, I have been avoiding googling it.
