Former captain Gareth Llewellyn says Wales' Six Nations class of 2012 are "looking as dangerous as we ever have".
The forward, capped 92 times, says Warren Gatland's side go into Sunday's clash against Scotland in Cardiff with match-winners throughout the team.
He added: "We're not just dependent on one or two players to do something special for us.
"We've got them right across the park now, so I think we're looking as dangerous as we ever have."
Llewellyn, who made 82 Wales starts and 10 appearances off the bench, believes Scotland could make life very difficult for Sam Warburton and his team-mates at the Millennium Stadium.
Andy Robinson's side spurned a glut of chances as they lost 13-6 to England at Murrayfield in the opening round.
That gives Llewellyn cause for some concern, but he is optimistic that Wales have enough talent to see off the visitors in the wake of their 23-21 win over Ireland in Dublin.
He said: "We've got a very intimidating set of backs at the moment, as big as any backline in world rugby, I would suggest.
"And the more time they have together the better they'll get.
"So to have someone like Hooky [James Hook] on the bench is a bit of a bonus really.
"He can't force his way into the team, but I've never seen in recent times as many match-winners across the park - guys like George North, [Alex] Cuthbert, Jamie Roberts, Warburton, [Toby] Faletau in the back row, Gethin Jenkins coming back in [at prop].
"We're not just dependent on one or two players to do something special for us.
"We've got them right across the park now so I think we're looking as dangerous as we ever have.
"I share the optimism from a Welsh point of view because I thought we played very well against Ireland, as well as I've seen us play for some time. So we have to be confident going into it.
"However, I don't think it's going to be a walk in the park. I think Scotland are a very capable side and sooner or later they will start finishing off their chances when they keep creating them.
"So I'm optimistic because of our performance, not the Scots' lack of, really."
