Man of balance (4)
I believe the answer is:
alan
'man' is the definition.
'of balance' is the wordplay.
'of' indicates the answer is hidden within the clue.
'ALAN' is hidden in the letters of 'balance'.
(Other definitions for alan that I've seen before include "Boy" , "A.A. Milne's first name" , "Sir -- Sugar (The Apprentice)" , "English historian/poet" , "- Bennett, English actor, dramatist, writer" .)
