If you don't have ANY Kiwame tantous yet, I suggest getting a few as soon as possible, because even at low levels, Kiwame tantous are awesome (once you refine their stats up)--lightining-fast speed and the ability to carry two projectile troops, plus all the striking power and leadership of a tachi (but with much shorter repair time than the bigger swords.)  Plus, since their level is so low, they won't trigger high-level KBC, and you can use them to lower your team's average level for maps that have a level limit.

However, once you have enough kiwames to field an all-kiwame team, it becomes less urgent, and you should consider how many kiwame kits you want to set aside for future kiwame types, and whether you need to keep a bunch of non-kiwame tantous so you can grind 7-4 long/easy for Juzumaru.
