Tango in ballroom dancing, women's ultimate hit? (6,4)

'ultimate hit?' is the definition.
(the hit or blow which kills someone)

'tango in ballroom dancing women's' is the wordplay.
I cannot really see how this works, but
'tango' could be 't' (phonetic alphabet: alpha, bravo, charlie etc.) and 't' is found within the answer.
an anagram of 'ballroom' is 'moralblo' which is located in the left over letters.
'women' could be 'w' and 'w' is found within the answer.
No letters remain.
This explanation may well be incorrect...
