Eve Muirhead and wheelchair skip Aileen Neilson were at the last Winter Games in Vancouver and came away with disappointing results as a 19-year-old Muirhead skipped her team to seventh place, while the wheelchair team slipped from silver medallists four years earlier to sixth.
Muirhead and her team of Claire Hamilton, Vicky Adams and Anna Sloan are now world champions and previous European champions, successes which only spur her on.
"This is unfinished business for sure," said Muirhead, who also has a record-breaking four world junior titles in her collection. "It's the only medal I'm missing. We've had a great last season, but that's last year and we've got to move on.
"Vancouver was a big eye- opener for me. I was still young and maybe thrown in at the deep end a bit. I was the young one in a team who were older and more experienced than me. Now, I'm the experienced one in this team, so it's a complete opposite."
For Neilson, who leads the wheelchair team of Gregor Ewan, Robert McPherson and Tom Killin, there is the added motivation of trying to come back from a couple of disappointing seasons.
"For me, the unfinished business is knowing we're capable of better than our results have shown - in Vancouver and since. But we've introduced a lot of new things in the last couple of years, so you can't expect to be at the top of the tree all of a sudden. Sometimes you've got to go back before you can take a step forward.
"In Vancouver, I was throwing last rocks but not skipping. Having skipped now for over three years, I've got a lot more experience and I'm going to be much more confident and much more positive. This will be the pinnacle event and I really want to show just how good we are this time."
Neilson is also aware of the huge boost Paralympic sport received last year.
"The coverage that the Paralympics got in London was just amazing and the large number of people who have come up to me more aware of people's ability and what they can do, can only be good for all sport. They're not as frightened to ask questions now."
As the build-up to Sochi continues, Muirhead, pictured, is set to become one of the faces of Team GB and she is ready for that.
"People are saying we'll be under pressure going in as world champions, but we think that's a positive," she said. "If I had the choice between going in as world champion or not world champion, I'd choose world champion all day long. Having not got the results we wanted in Vancouver is a wee bit of a blessing in disguise now, but at the time it's not like that. I learned a lot and I've changed a lot. Now we've shown we can win major championships and we're in the best possible shape.
"I really enjoyed Vancouver, but I went there to do better than we did. I know I would have enjoyed it a lot more if we had been competitive."
