The trio of southside rugby clubs got their campaign off to the perfect start on Saturday.
While GHA looked shaky at points during a 29-14 win against Dalziel, Whitecraigs and Cartha both overwhelmed their rivals.
Dumbreck side Cartha QP made light work of Greenock, winning 62 -13 in their home fixture.
Whitecraigs meanwhile, dominated Dunfermline at West Lodge 51-6.
First half tries from O’Hare, Henderson, Kellock and Auld secured the bonus point before half time, while Jamie Auld scored his second after the break and a Tane Jericevich conversion put the final touches on a 29-14 win.
Four teenagers started the match against Dalziel on Saturday, including James Malcolm, who played alongside brother Donald. Head coach Gordon MacPherson was delighted with his debut.
He said: “There were some good performances like James Malcolm, who played his first game and showed why a lot of people are talking about him.
“He is one for the future and is part of the Scottish Academy — a good, upcoming prospect. Declan Larkin was around the club last year and will hope to push on a bit this season.
“We have some good young guys and that’s what we are trying to do — bring them on so they get some experience”.
Meanwhile, tryscorers Cook, Scott, Hine, Noble, Crozier and Nellaney, as well as kicker Andi Black, helped Cartha demolish Greenock.
At West Lodge, the large crowd in attendance celebrated as captain Iain Laidlaw crashed over the line in 25 minutes for the opening try.
Dunfermline struck two penalties but eventual man of the match Ross Macdonald extended the home side’s lead to 12-6, at which point the game opened up as each team had a player sent off, with Craigs losing a man to a red card and the Dunfermline man receiving a yellow.
But it was Ally Stevenson who made the extra space count when he scored a try, followed by another Moffat conversion to make the score 19-6 at half time.
An early Moffat penalty and Grant McGibbon try set the tone for a second half onslaught.
Jamie Howarth, Phil Nicol, Ryan Moffat and Ally Stevenson all added to an impressive tally on the day
Coach Jim Barrie commented: “I was very pleased with the result but complacency can not set in and every player has to compete for their position”.
Next week, Whitecraigs visit West of Scotland, who lost 22-10 to Falkirk on Saturday. GHA will visit Dunfermline and Cartha travel to Dalziel.
