LF Bloodletter with +3 Desperate Measures and +weapon dmg

Looking for Bloodletter with +3 Desperate Measures and 1, some, or all of the following:

+weapon dmg
+splash dmg/size
+shotgun dmg
+torque dmg
+torque crit
+grenade dmg
+5 grenades
+Dahl dmg/crit

I have bloodletters with +hp, low-level stop gap, and a bunch of other things to trade for the right mod.
