Sidoli will be at the heart of that crucial set-piece contest when Wales target a fourth successive RBS 6 Nations win on Sunday, edging them ever closer towards a Grand Slam triumph.

Wales, despite a poor Murrayfield record over the last 20 years, travel to Edinburgh as clear favourites.

But the lineout is one area where Wales must improve, given that they have lost 11 on their own throw during RBS 6 Nations victories over England, Italy and France this term.

It is a statistic that puts Wales bottom of the lineout league, and Scotlands revered second-row pairing of Scott Murray and Stuart Grimes could capitalise.

It is the one area of the game that is most analysed and most trained for, said Cardiff Blues forward Sidoli.

Every team is studying every other side in detail and trying to work out ways of either winning their own ball, or nicking opposition ball.

Scotland have got the whole package at the lineout, defensively and offensively.

They obviously spend a lot of time in that area, and are regarded as one of the best.

Murray is very intelligent and makes a lot of good decisions, while Grimes is deceptively good on his feet, and they are both abrasive players.

Theyve got a lot going for them as a pair, and it will be a good contest.

Wales received a boost earlier this week when hooker Mefin Davies was declared fit for the Murrayfield encounter after recovering from a thumb injury, and although the statistics suggest lineouts are a potential Welsh weakness, Sidoli remains upbeat.

It has gone pretty well for us, both defensively and attacking-wise. Obviously, it can always be better, but there are things that we are trying to do and work towards - its getting there slowly, he said.
