A friend interdicted me yesterday while I was in a PvE Krait I use for assassination missions. In total it has 8 reverb torps, 4 deep cut torps, and 2 long range Hammers. His ship was a PvP Krait with frags and plasmas. I fired off all 8 reverbs in 4 volleys of 2 and took his shield gen down to 28%, so I think there's some quality control issues at the torpedo factory. Anyway, I used the 4 deep cut torps and that dropped his shields, but because I stupidly didn't target his shield generator it stayed at 28% while a bunch of his other modules were shredded, like his FSD and PD. I used the hammers to finish off the shield generator, but ran out of ammo when his hull was down to 16% or so. Meanwhile he had taken my hull to about 40%. A last minute ram finished him off with me at 20% hull.
The neat thing about torps is they keep circling for what seems like 5 minutes. It was one of those "forgotten" deep cut torps that really hurt his ship.
Final note is that that was the best fun I've had in this game.
