Incarna changed they way probing works, though I'm not quite sure of the specifics. What I do know:
-All 8 probes now return a result
-It is no longer possible to be unprobeable, though it's still supposed to be hard to get a result
So, what's the best probe formation? I would assume a cube, but I've heard suggestion that that may not be optimal?
I have a few unprobeable gang-link ships hanging around--what's the ETA of hostiles pushing my shit in once I uncloak and fire up the links, assuming I continue to use an old unprobeable fit?
