Choosing to make a point with light heart (6)

I believe the answer is:

opting

'choosing' is the definition.
(I've seen this in another clue)

'make a point with light heart' is the wordplay.
'make' indicates anagramming the letters.
'with' says to put letters next to each other.
'heart' means to look at the middle letters.
The middle letter of 'light' is 'g'.
'point' is an anagram of 'optin'.
'optin'+'g'='OPTING'

'to' is the link.

(Another definition for opting that I've seen is " 'Choosing, plumping (6)'".)

I've seen this clue in the Evening Standard.
