I would have let one of them keep the sonic arrow. Probably Zangetsu, since Bows were a more important part of a samurai's arsenal than swords.

I agree with Sigurd having the twin-balled flail and Marika having a scimtar or two. Those choices fit well with both the themes of the suits and the characters.

I disagree with Locke on Duke having a huge sword though. A giant Final Fantasy style sword does not suit the Duke armour or Ryouma's character at all. Ryouma strikes me as the kinda guy who would fight smart and go for quick surgical strikes and competent defence over brute strength and smashing everything. I actually think a longsword and shield combo, like KR Mars, would suit Duke's knight theme and Ryouma's character best. And Duke is the one set of powers that really has to fit it's user to make any logical sense, since Ryouma directly designed the suit for himself.
