Can I give you a personal recommendation about sending kiwame to training? Just send them as soon as possible!!! No need to level them all the way to level 80~90 before sending them to training, really!! As soon as they come back max their stats in the refinary and even low leveled kiwame tantous can train at map 6, with the advantage of one more troop slot and better stats. If you prefer map 5-4 they can even avoid long ranged phase! There are far more advantages to sending them off to their kiwame training than not. The amount of experience necessary to level a kiwame form lvl 1 to 35 (actually ~35.5) is exactly the same you need from lvl 60~99 of a normal kiwame, but it'll just be easier. Leveling kiwame tantous only gets hard and takes long after lvl 35, before that they level really fast! I'll show you a graph (Level x Exp until next Lvl) to illustrate it ;)

I really suggest you give it a try and send one kiwame to training before leveling it and feel for yourself how much easier it is ;)

And about world 7, it's much better to grind kiwame tantous there, other swords might lose too many troops and it's quite expensive >.<
