Ah yeah...11 base damage could nicely damage a speeder. And I would pretty much just clone the 74-Z if I were making a STAP.
I wonder, how would autofire work with Improved Reflect? Obviously you can Reflect any and all hits from an autofire weapon, so theoretically, with enough Threat or Despairs, you could redirect two (or more) hits from an autofire weapon, yes? So for example, Qui-Gon's already got his dukes up, the STAP rolls a double Despair on its ambush, and it goes boom.
'Course, such a thing could be a much more narrative construct as well...GM throws something at the players, Qui-Gon's like "I got this!", makes a Lightsaber check, rolls a Triumph.
