SunDevil-
Havn't had a chance to look at your files yet, probably not till tomorrow (I am still at work
and will be for quite some time).
I believe Mephisto meant these were not used in any of the design files.
What I meant below was that even if you include boarding ships, cloaking, ramming warheads, etc. the AI will not use them - try it in the simulator or at any point in a level 3 game, check out the AI fleets - none of them will be cloaked, not even recon sats. So yes, I pushed those techs to the very end of the research file where my "catch-all" clauses are located.
