Firm undergoing cyclical readjustment with supreme competence (6)

Ross

I believe the answer is:

ablest

'with supreme competence' is the definition.

I don't understand the rest of the clue.

(Other definitions for ablest that I've seen before include "Most capable" , "Like pupils in top stream" , "Most suitable" , "Are highly favoured like" , "Most proficient" .)

I've seen this clue in The Independent.
