But that leads us to the crucial problem that will confront Scotland in Cardiff on Saturday: can they win the ball?
Rugby supporters heading to Principality Stadium for the NatWest Six Nations opening round clash between Wales and Scotland have been warned they risk missing kick-off if they do not heed warnings to "get in early".
While Halfpenny's perceived lack of attacking threat has been overplayed, his try-scoring record of 12 in 78 Tests is significantly bettered by Scotland's rapier No15 Stuart Hogg who has 17 tries in 55 Tests.
Wales, who have selected ten players from the in-form Scarlets including fly-half Rhys Patchell, have won nine of their last ten matches between the teams but perhaps significantly Scotland were victorious in the most recent meeting. Much is expected of 20-year-old full-back Jordan Larmour and 21-year-old winger Jacob Stockdale, who will make their Six Nations debuts today against France at the Stade de France.
"The way they've been playing - that was a performance borne out of respect for them", said Wales skipper Alun Wyn Jones.
"Getting the bonus point was pleasing as well and we probably left two or three tries out there on the pitch, so there is some improvement for us to do there". Previous year more than 10,000 watched their match against Scotland in La Rochelle and France are relatively settled in terms of personnel, having finished third at the World Cup.
"It was an afternoon I was expecting with the way we have trained the last couple of weeks", Wales coach Gatland said.
The visitors could only muster a Peter Horne try and a Finn Russell conversion.
Scotland scrum-half Ali Price sees his long pass intercepted by his opposite number Davies, who raced 50 metres before diving into the corner to score.
"We had tempo but not accuracy", Scotland captain John Barclay said.
The interval did not provide a fresh start.
Unlike Scotland, Wales wings Evans and new cap Josh Adams were making big yards on the outsides.
Wales finished above only Italy in last year's championship but expertly marshalled the final 30 minutes and will be full of confidence when they travel to back-to-back champions England next Saturday.
Any hope of a Scottish revival ended with a laboured exit from the second half kick-off which eventually saw Wales counterattack and Barclay was penalised, Halfpenny kicking an easy penalty.
LEIGH HALFPENNY bagged a 24-point haul - including two tries - as Wales defied all expectations by handing the Scots an absolute hammering. You grow up watching the Six Nations games and you hear the noise on the TV as a fan, but stepping into the arena as a player, it is totally different.
"If you take Italy's results away from the tournament - and I don't wish to do that but sometimes you have to just because they still have a wee bit to catch up, although Conor O'Shea will bridge that gap - there was only one away win in the whole tournament previous year".
