Excellent spinner following advice (6)
I believe the answer is:
tiptop
'excellent' is the definition.
(I've seen this before)
'spinner following advice' is the wordplay.
'spinner' becomes 'top' (something that spins).
'following' means one lot of letters go next to another.
'advice' becomes 'tip' (I've seen this before).
'top' after 'tip' is 'TIPTOP'.
(Other definitions for tiptop that I've seen before include "The pinnacle of perfection" , "Best of its kind" , "Excellent, super" , "The very highest point" , "Very fine" .)
