Fu and Roshi is a jinch supports. And from these two as supports, Roshi is better. Yagura is pos2 ninja in best case (in our version). I would prefer recommend normal Yagura over Edo. And Han is position1 ninja. So it really depends on what you need ^^ From all these, i would recommend Roshi. Since it can actually be used in pos1 with water main (like others uses Shisui), and later you c@n use him as support. Unless, you don't have decent pos1 ninja, and don't plan to get Edo Minato/Naruto anytime soon, then i would go for Han. Tho i just faced him in arena, and vs low powers, so maybe someone can comment on this.

Of course, one is to chose a ninja from a treasure, and other is to actually pull him. Good luck o/

Edit: Yeah, I forgot Edo Yagura got a skillbreak haha ^^. Looking to a future, he might an option to have. o/
