Best spinners (4)
I believe the answer is:
tops
I believe this clue is a double definition.
'best' is the first definition.
(I've seen this in another clue)
'spinners' is the second definition.
(things that spin)
(Other definitions for tops that I've seen before include "Betters" , "The best" , "Max - spinning toys" , "Surpasses; toys" , "Exceeds" .)
