Melrose, playing without their Scotland under-20 squad members, looked the likely winners, after knocking out the Kings of the Sevens leaders, Jed-Forest, in the first round and then disposing of Boroughmuir in the quarter-finals with a 33-7 win.
But it was in the second of the semi-finals that Melrose laid down their title winning credentials by overwhelming a Watsonians seven that has performed well on the Borders circuit, try doubles by Richard Mill and Jason Baggott helping the Greenyards men to an unexpectedly high 52-5 win over the Myreside team.
Gala, meanwhile, came through the top half of the draw by defeating Hawick 24-19, after extra time, in the first round before producing a a startling 41-12 victory over Edinburgh Accies in the quarters. Then in the semi-finals Gala had too much pace for hosts Kelso in their 24-7 win.
In the final Gala struck first with a Keith Young try but thereafer it was Melrose who dominated with fast sevens rugby that gave them a 29-5 interval lead. Then, despite a try for Gala by Rex Jeffrey after the break, Melrose piled on the scores as Bruce Colvine completed his hat-trick and player of the tournament Mill his brace for a 57-19 victory.
