Paul Voy led the way with a hat-trick of tries as Preston Lodge completed their unbeaten league campaign in spectacular style on Saturday.
The RBS East One champions went into the match with Langholm having won 17 matches out of 17 and they made it 18 out of 18 with ease.
They saw off the Borderers 101-5, putting them to the sword by running in 15 tries and putting the boot in by kicking 13 conversions.
Voy scored three of the tries with Fin Hughes grabbing two and Jonny Brash, Darren Eales, Paul Glynn, Graeme Patterson, Euan Higgins, Blair Robertson, Dave Lockie, Dale Gordon Chris Dixon and Jason Riley all crossing the try line too.
Preston Lodge have dominated but great credit goes to RHC, North Berwick and Dunbar who pushed them hard for large chunks of 2013/14.
The Focus for Preston Lodge captain Blair Cowan and his triumphant players now turns to the RBS Shield final against Caithness at Broadwood on April 19.
If they can win that one and then the East Lothian Cup final against North Berwick on April 26 they will have collected four trophies this term without losing a game.
