My only "dupes" are level 63 Chitose and Chiyoda AVs (leveled almost exclusively through exped 36), level 20 Taigei, and a level 90 U-511. I used to have two sets of Imuya, Goya, Hachan, and Iku, in both of their forms, SS and SSV (not applicable for Imuya of course), but scrapped them in the end. Since I merely grind in world 5-4, I have no use of SS tanks anymore. I have the same policy as yours. Though recently I've started grinding Hiryuus, Souryuus, Oois, KTKMs etc. for their equipment. Actually I've always ground for equipment, starting with Isuzus for Type 21 radars very early on.

Oh yeah, I believe that B44 quest was a pretty dreadful one indeed.. :/ Not a fan of the monthly 5-1 quest either, but screws!

Good luck with E-4, Andere kc! ^_^
