I think the dupe rate in Sage treasure is very low, but you hardly ever pull Sage at 120 pulls. You either get him at 60 or 180 atleast that is what I have noticed. Since you already have KK Gaara you probably want the annoying SN, KK, WM, and either SS, Gakido, or Hanzo team. If you have either Hanzo, Gakido, Killer Bee, or Sailor Sakura I would pull for Sage Naruto if you have enough scrolls. Really depends on your ninjas though. Personally I saved for Roshi and he is very strong. If you get the time post a screen shot of your current ninja and summons.
