Spikes demon drink with soda, principally (7)

Ross

I believe the answer is:

impales

'spikes' is the definition.
(I know this)

'demon drink with soda principally' is the wordplay.
'demon' becomes 'imp' (I've seen this in another clue).
'drink' becomes 'ale' (type of beer).
'with' is a charade indicator (letters next to each other).
'principally' indicates taking the first letters.
The first letter of 'soda' is 's'.
'imp'+'ale'+'s'='IMPALES'

(Another definition for impales that I've seen is " Runs through".)

I've seen this clue in The Telegraph.
