I figured flechette or Ex-Explosive, so that's not a surprise. My soak should be 26 (14 Armor + 7 Body + 5 flechette), and the extra hit on the dodge drops it down to 14 DV to soak.
Avg. soak: 8 2/3
Avg. +1 from edge dice
Avg. +1.44 from exploding dice.

I won't spend edge. At worst, I'm not going to die from the attack, just be really, really sore. I can also spend edge later to reroll 1s.
