Mirsky was knocked out of the 2010 Gold Cup in the quarter-finals by Berntsson and more than avenged for that defeat this year. He said, "We are over the moon with winning two titles in a row. We've never done that well in Bermuda and we've never had many Tour wins so this is fantastic, we're really on a roll. I'm so proud of the way the team sailed this week, everyone just knew what they were doing on board and we felt comfortable and confident. Johnie really tested us in the final which made for some great sailing.
"We are now close to Ian in the points and we have a big chance for the world title so we'll be fighting for it! Hopefully we can keep on this roll and win in Malaysia too."
Berntsson, who picked up 22 points for his win here to give his season a huge fillip, commented, "We're disappointed but it was a great performance overall. The finals were really tight and we felt like it could have gone either way. We collected too many penalties though and lost the last pre-start and that really cost us. Torvar did a great job and was tough to beat so congratulations to him.
"Maybe in an hour we'll be happy but right now we're really disappointed because we came so close to winning. We've got a three year aim to finish on the podium so we're progressing well towards that.
"We're happy to get an automatic invite to Malaysia. That was our goal."
Mirsky's other arch rival for the Championship is Bruni who was involved in the Petit Final earlier in the day. The first match was really all over in the pre-start, Robertson picking up two penalties which forced him to take an immediate penalty turn and hand Bruni a sizeable lead that he maintained to cruise to a 1-0 lead.
Robertson made a cleaner start in the next match and managed to stay within touching distance as they approached the first mark. Despite not having raced the IOD class before, Bruni's boat speed had been strong all week and he managed to open a gap on the first downwind leg which he extended on the final lap through to the finish for a deserved win.
Bruni, who now sits in second place in the Championship, just six points adrift of Williams, said, "It was a really intense regatta for us. We came here knowing it was going to be tough - we didn't know the boats but I think we adapted really well to them.
"The most important thing is that Ian didn't go through to the semi-finals and we gained valuable points on him. Everything will now be played out at the Monsoon Cup and that was our aim heading into this regatta. We truly believe we can win in Malaysia."
Robertson, who remains in tenth place overall, reflected, "It was a good result for us overall, the team have done a great job and if anything I let them down in the pre-starts today. It's disappointing to lose the semi-final and then the petit final but it is what it is.
"It's been an interesting year for us, very much up and down but we've learnt a lot and we are hoping to just keep learning and take it all away and use it to improve next year."
Last year's Tour leader going into the Monsoon Cup Mathieu Richard drops down to ninth in the overall Tour standings and will not get an automatic invite to the Monsoon Cup.
The 2011 ISAF Match Racing World Championship will be decided at the Monsoon Cup which takes place from 22-27 November in Kuala Terengganu, Malaysia.
