Simon Easterby knows good defence wins matches and that his side can build some early season momentum with two Magners League matches this week.
Easterby and his Scarlets side recorded a 16-9 win at Ravenhill to get thier season off to a near perfect start in less than perfect playing conditions.
Faced with near gale force winds and torrential rain, the Scarlets' defence held firm for 80 minutes, with all of Ulster's points coming from the boot of full back Clinton Schifcofske.
"Our defence was excellent again, which is hugely encouraging and a big positive for us," said Easterby.
"There was a huge amount of character shown by the boys because regardless of the conditions this is always a tough place to come and play.
"We have got to take this win now and build on it."
The victory means the Scarlets finish the first weekend of the Magners League season in second place behind the Ospreys. They have matches against The Dragons and Connacht in the next seven days and a chance to build some early-season momentum.
The skipper, however knows that nothing can be taken for granted, he said: "We have got a tough week, (Dragons away on Wednesday, Connacht home on Saturday), but it will be great to finish off with a couple more wins.
"We are not fancied by many people, but we are just keeping focused on our job.
"And if we can perform like we did tonight I am sure we can get more positive results like this one."
As the countdown continues for RWC2015, Tournament Chief Executive Debbie Jevans visited the Millennium Stadium to discuss preparations for the eight matches and reveal the positive news that 100,000 tickets for games at the home of Welsh rugby have sold in the last seven days.
Jason Harries is targeting a first win on the World Series circuit this season with Wales. The series returns to action this weekend in Dubai where Harries is part of a team hoping to build from its efforts in round one in October.
Wales skipper Jevon Groves says his side have addressed a few points from Gold Coast and aim to 'hit the ground running' in the next two rounds of the World Series, kicking off with this weekend in Dubai before heading off to South Africa next week.
Wales Sevens manager Steff Thomas is hopeful his side can build from a quarter-final spot in the opening round of the World Series in Australia when his side take part in the forthcoming double header in Dubai and South Africa.
