He was then rewarded with a full-time contract, and midway through 2007-2008 he was well established as Edinburgh’s regular at open side.

On day two of the tournament he scored his first try in the 40-7 cup quarter-final loss to England. He went on to earn his second sevens cap a week later at the IRB GMF Paris Sevens.
