If I may nitpick, Hime weapons that have a GOOD FLB. Generally what you're looking for is triple-skill or double-Assault (Assault and Pride in the same weapon).They're not very expensive to buy anymore, so I buy them for fodder.The "which Soul should I use?" thread should answer that.You have Raiko and SSR Baal, so I suppose you're in good shape. As good as you can get without Thunder Aphrodite anyway. There's always Thor for Union Events, I guess. Or Dian from the next Miracle Ticket, if you want the best heals anywhere for some reason. Oh, and Marduk Awakening is coming up, she turns really good at that point I believe.
Since you run SSR Baal and Tyr, you might consider swapping Herc to Shingen. That'd speed up your team even more.
