Jamie Roberts has warned Wales cannot afford to adopt a "gung-ho approach" when they tackle RBS 6 Nations opponents Scotland at Murrayfield on Saturday.
Test matches between Wales and Scotland are traditionally open, high-scoring contests. Their last six championship meetings have harvested a total of 283 points and 28 tries.
Given that Wales have gone eight games without a win, desperation for an overdue victory could easily result in them throwing caution to the wind, and Roberts said: "Balance is key this weekend. We can't afford to take a gung-ho approach and chuck the ball around."
He added: "When we won 26-13 at Murrayfield two years ago, it was one of the most clinical performances we've seen from this Wales team, I think.
"We were outstanding for the first 50-60 minutes. It was one of those games where we worked very hard off the ball, and it paid dividends for us.
"We carried strongly and put them to the sword, and that's what we need to do again this Saturday."
Roberts, man-of-the-match on that occasion, returned to international rugby against England last week after missing Wales' four previous Tests - but he touched the ball just five times.
