Ya ya Sry. I just realised that my whole point did not get there. What I was planning to say is that sasuke may learn To control sage jutsu once he is aware of it (i know he is aware of it, I just meant him using it) and that might match up with naruto power level.
And I was just pointing it out in sasuke's case. Ofcourse the juugo's cell is compatible to all, infact the curse seal was done from studying him.
