West Lothian IBC failed to shine in their opening match of the Premier League.
Despite home advantage at Livingston the defending champions crashed to a 12-shot defeat at the hands of Midlothian.
Match sharpness was below par for the most part across a home team that failed to cope with the enthusiasm of Midlothian.
Midlothian arrived with the notion that WL could be vulnerable in the opening match of the season and exploded from the blocks to race into a 17-4 lead after three ends.
Midlothian stayed strong to dominate the first seven-end phase, 31-10 then added the second, 28-20, before WL showed some resistance to capture the third, 25-18.
WL lost out in three of the four rinks but managed one excellent outcome with Mark Allison skipping Paul Lynas, Raymond Logan, and Jamie Gracie to a commanding 23-11 win.
The rinks skipped by Neil Speirs, Calum Logan, and James Speirs all lost.
Neil Speirs and his three of Bryan Cooper, Dougie Mitchell and Des Hagart carded a five to lead 7-5 but only managed to count at five of the 20 ends played.
