A True Sage

i don't for a moment believe that tsunade would have any difficulties maintaining sage mode she is a legendary medical ninja her skills in such are so skilled she would never have any problems balancing her chakra

and being that she is both a senju and an uzumaki she would not have any problems with chakra level
