Scotland coach Frank Hadden hailed the last-gasp victory against Italy in Rome as more important than those against France and world champions England.
The Scots ended nearly four years of misery on the road when Chris Paterson kicked a 77th-minute penalty to hand his side a long-awaited success away from Murrayfield and end the campaign on a high.
The 13-10 win at the Stadio Flaminio looked unlikely when Mirco Bergamasco scored a try after six minutes but Paterson crossed five minutes later and added the conversion before Gordon Ross dropped a goal just before half-time.
Ramiro Pez, who had converted Bergamasco's try, squared the match at 10-10 midway through the second half but Edinburgh star Paterson coolly slotted the decisive penalty.
Hadden said: "In many ways I think this win is more important than the two home wins. I think everybody in rugby is aware of how difficult it is to win away from home.
"I'm not quite sure what sort of value you can put on home advantage - but it's certainly significant.
"The progress Italy have made has been outstanding and I said this week they'd played better than us this season so we knew it would be tough.
"So we're absolutely delighted to get away with the win, which I think we deserved on the balance of play.
"Although some of our attacking play was a bit rusty, because we haven't really done much in the past two games, I thought the ambition and build-up was good.
"That's important because there's no doubt that our attacking play is a work in progress.
"I'd like to also pay tribute to the work Alan Tait has done because the defence was once again excellent and also full marks to Shade Munro (forwards coach) for the work done with the line-out because a week is not a long time to turn that around.
"I'd every confidence that we could produce the goods and I thought the line-out was first-class.
"I'm delighted with the quality of the coaching staff that I've got and I'm also delighted with the quality of the squad that I've got.
"I said it last week after defeat (to Ireland) and I mean it - I'm happy with where we are.
''There's tremendous spirit in the squad and a lot of that must go to Jason White as captain.''
Italy coach Pierre Berbizier believes a lack of maturity cost his young side dear.
The French legend has overseen plenty of progress with the Azzurri in his first season in charge but they were unable to secure a victory in their five matches.
The draw in Cardiff last weekend - the first point Italy have ever claimed in the tournament - was however indicative that Berbizier's men are on the right tracks despite once again picking up the wooden spoon.
"We had a good reaction after half time after Scotland had gone ahead just before the interval. We did well at the start of the new half,'' he said.
"We got level and we had a couple of chances to get a try but we didn't take them and that is a problem when you have a young side.
"It's normal when you have a young team to have this lack of maturity and we must not forget we were playing against a team competing at a very high level.
"When you get chances like that you must take them, especially when you have a small amount of possession as we had.
"When you don't have the ball a lot, it makes it difficult to threaten Scotland. We had to attack from our own pitch a lot and that is difficult.
"So, although we have played well in a lot of this championship we have not won a game and that is what I had as a target.
"We need to keep working hard to achieve this but at least we saw that the fans were happy and that is important for the future.''
