if you're going to do it, heed WWHSD and take the int agent
you have 3 crew slots; it'd be a crime not to
just be aware that no one uses eh because it counters the deci's fatness. It directly shuts off isanne and replaces predator's action-independent re-rolls. If you're literally going to roll with it, you will be sacrificing your ability to be a stupidly boring yet effective PWT to be a rolling pin of awesome.
so to make this work there is always oicunn with EH, ysanne, and experimental interface. ram to do damage, get an evade at the start of combat, EI for the EH, barrel roll out of arc, or into position for next turn ramming. throw vader on there too and its a fair bit of non-avoidable damage. This way everything triggers off of ysanne just like the vanilla Engine upgrade shenanigans.
