Is it possible to use gnw Choji instead of regular one?

No, I mean what I said. It might hurt you to miss on some buffs because you kill those archers too quickly with aoe hit of GNW Choji, and as I tried this team, often I found that I'd rather have the prompt mystery of regular Choji...

Besides, I think this guide is wrong... Hidan must not be allowed to do his "aoe ability", otherwise he tags the whole team and wipes you with standard attack, because your healers are too slow to get rid of that and you can't use your mystery heal because next round Chikushodo is gonna tag you again.
