i say the hyugas but since they don't know about hidan that could be a problem but all sasori's jutsu can be countered by gentsle fist jutsu and hidan is next to useless as he cant touch neji or hiashi and one or two taps couldp paralayse him for the entire fight or hiashi could start fighting sasori and tell neji to take care of hidan after using gentle fist on him neji proceeds to remove his head after finding out he's immortal then dumps it somewhere and goes to help his uncle (who would doesn't need it b the way) destroy sasori GAME OVER
team hyuuga mid-high diff (but mostly mid)
