Tbf I seriously doubt Zoro's weakest move is a Santoryu move. I also can't see Kyoshiro brushing off a rengoku onigiri as easily as he brushed off 720 pound cannon.
Now on the other hand, maybe an argument could be made that rengoku onigiri is one of his weaker santoryu moves.

The number of swords has nothing to do with it kaen is used with one sword so is shishi son son
