They are in action in Pordenone against their Italian counterparts tomorrow night, with four changes made from the starting XV that took on the English at Netherdale.
Chris Dean, a try-scorer in the 48-15 to England defeat two weeks ago, and Neil Herron return to Scotland Sevens to prepare for the tournaments in Japan and Hong Kong.
Last season's Scotland Under-18 captain Richard Taylor comes in at centre. Moving from the bench to the starting line-up are scrum half Murdo McAndrew, prop Phil Cringle and flanker Lewis Carmichael at blindside. Buchan Richardson and Ben Vellacott are among the replacements, as is the stand off George Horne, brother of the Scotland back Peter Horne.
Sean Lineen, the head coach, said: "At 10 - an area where we've not had a lot of strength in depth - we've got Ben Chalmers and now George Horne is back. They're both young, are great guys to work with and have another year at 20s so there's a lot of room for them to develop.
"There was certainly an improvement in our performance when we played England and we're looking for more in what will be a tough game against a very passionate Italian side.
"I have every confidence in our boys. They're learning all the time and it's great to see their enthusiasm and commitment. There's a lot more to come from these lads."
