Scotland international Marcus di Rollo believes continuity has been the key to the team's improved fortunes in the RBS 6 Nations Championship this year.
The Scots have already beaten France and England at Murrayfield after winning just one game in the previous two RBS 6 Nations tournaments.
Under head coach Frank Hadden there has been a renewed optimism in the Scottish game after the disastrous reign of Matt Williams, which was ended a year ago by the Scottish Rugby Union after a run of three wins from 17 Tests.
But the former Edinburgh Gunners boss has steadfastly refused to make changes to his squad for change's sake.
And the 28-year-old Edinburgh centre Di Rollo is convinced that level of consistency in selection has served Scotland well.
He said: "Continuity this year has been a huge bonus. Frank has always been an advocate of that and the fact similar 22-man squads for the autumn Tests and the Six Nations have been used has helped us.
"It is often difficult when you don't play together all the time.
"You have to come in, have the odd game and then go straight out again.
''It is difficult to form partnerships in situations like that.
''Having the continuity has been a huge part of our success this year.''
Scotland claimed their first Calcutta Cup success since 2000 when a Chris Paterson-inspired display saw them run out 18-12 winners over the world champions.
The win came a fortnight after the defeat in Wales for the Scots and the Edinburgh centre concedes a two-week break before the crucial trip to Ireland this weekend is a double-edged sword.
Di Rollo said: ''Maybe the two-week break has come at the wrong time after the win over England.
''But the good thing is we will be having the final matches back-to-back.
''The Italian game will come straight after the Irish trip.
''Another positive for us was, while we did really well and got the win against England, we came out of it injury-free.
''We will also have Scott Murray available after suspension meaning further competition for places, and that can only be good.''
England flanker James Haskell insists he will be pushing as hard as possible to be back from a toe injury in time to make his case for a spot in Eddie Jones' side looking to defend their RBS 6 Nations title next year.
