Chooses spinning tops (4)
I believe the answer is:
opts
'chooses' is the definition.
(I've seen this before)
'spinning tops' is the wordplay.
'spinning' indicates anagramming the letters.
'tops' is an anagram of 'OPTS'.
(Other definitions for opts that I've seen before include "Chooses from a range of possibilities" , "Picks needed" , "Makes choice from post" , "Selects between alternatives" , "Elects" .)
