Breslin will line up three horses at today's rescheduled Oamaru Cup day on what is expected to be a heavy track.
The trainer brought his team south in the hope of avoiding the water-logged tracks of the lower North Island.
The Ashburton track has been rated in a heavy11 for the past two days.
Though his trio of Salamanca, King Cougar and Wafer appear to have good heavy-track statistics, none of them are at their best on heavy ground.
It would be a concern to the trainer if the Ashburton track was still rated as heavy11 by race time today.
"That is why they are down here - they are all dead and slow track horses,'' Breslin said.
"We just have to hope that Ashburton is not quite as deep as the tracks back home.
"That is why we brought them down early [leading up to the Grand National carnival], with the hope of getting a run on a better track.''
Breslin's three are well-placed in their races today. They have been competing in strong company in the lower North Island and have arrived south in excellent order.
"They are all in the right condition to win,'' Breslin said.
"They are all capable gallopers.''
Breslin has King Cougar aimed at the Oamaru Cup-Winter Cup double, which carries a $60,000 winner's bonus.
King Cougar has excellent form after racing consistently in strong open handicap fields in the lower North Island.
The Alamosa 5yr-old has had eight starts on heavy tracks for two wins and four placings.
Breslin said some of those runs were in weak company.
"King Cougar has managed to win maiden races and [rating] 65 races on heavy ground, but he is definitely a dead-track horse.
"If it was a genuine heavy11 he might struggle.''
King Cougar's backers could take some confidence in his ability to handle wet ground from his good last-start second behind Herengawe on a heavy11 track at Awapuni on July 7.
Salamanca, an 8yr-old, is in a similar position going into today's 1200m open handicap.
The horse is stepping back from racing in strong fields in the North Island.
Like King Cougar, much of his good form from his 19 starts on heavy tracks was earlier in his career.
"Salamanca, as he has got older, has not really liked [heavy] 11 tracks,'' Breslin said.
"He is probably a dead6 to a slow8 horse.''
Salamanca is one of two North Island raiders in today's open handicap sprint (1200m). The other is Tabard, trained at Whanganui by Kevin Myers.
The 5yr-old produced an excellent run for fourth, when beaten less than a length by Miss Lizzie, in his last start on a very heavy track over the same distance at Trentham on July 13.
Apprentice Kozzi Asano's 4kg claim brings Tabard's weight down to just 51.4kg.
Breslin will start his final runner, Wafter, in rating 65 company over 1400m in race 9.
The trainer does not have high hopes for her if she is faced with a heavy track.
"Wafter hates it wet.''
Wafter was unplaced in her first six starts on heavy going but has run third in her past two starts in such going.
Selfie, The Bumper and Stellacanto are scratched from the Oamaru Cup.
