Cranleigh are becoming a force in the SOCS Daily Mail Schools Trophy besides their excellence in schoolboy sevens.
A 29-17 victory over Brighton College launched the new campaign and follows on from victory over the same rivals to retain the national sevens at Rosslyn Park last March.
Cranleigh have put thoughts of a treble in the sevens next spring on the back burner to concentrate on the full 15-a-side game.

Andy Houston, director of rugby, puts the success – only four defeats in all forms of the game over the past 12 months in 45 games – down to hard work.

Cranleigh made a quick start against Brighton scoring twice in the first 20 minutes through fly half Sam Lubbock and captain Jamie Barden.
A third try, off an interception, by centre Harry Serjeant kept Cranleigh ahead at half-time 15-10.
