From my reading of the OP it seems that he was trying to escape from the Python after being interdicted. If Type9s can't ever escape from such an encounter then who'll want to trade in one alone? (sadly we don't have the NPC Wingmen discussed in the DDF)
Agreed.
This is what worries me about the planned updates to the AI. There are many players who trade with lower grade shields and no weapons in T-9s and other slow ships. If there's not a decent chance in escaping from an interdiction then this kind of trading will no longer be an option.
