Willie Mullins and Ruby Walsh dominated the card at Clonmel with a 13-1 four-timer from just five runners.
The formidable combination took the two feature races with Inish Island and Call The Police as well as striking with the highly-promising mare Annie Power and Sarabad.
They were denied a 100% record on the day when their final entry, Cadspeed, could only finish third.
Call The Police may figure in the Mullins team for the John Smith's Grand National after lifting the Derrygrath Chase.
Third to Bobs Worth in last season's RSA Chase, Call The Police (5-6) was too good for this opposition.
Leading two out after first Bob Lingo and then Magnanimity had made the running, he outpointed the latter by three and a half lengths. Forpadydeplasterer was third.
"He's in everything, including the Grand National," said Mullins.
"I wouldn't mind bringing him back to two miles either as he's such a good jumper that he'd be able to perform at that shorter trip."
Inish Island (11-10 favourite) enjoyed a cosy success in the Surehaul Mercedes-Benz Novice Hurdle.
The seven-year-old was last seen running second to At Fishers Cross in a Cheltenham handicap and he went one better under a confident ride.
He brushed aside Venture Capital, his only serious rival, in the closing stages to score by two lengths.
Inish Island was cut to 14-1 from 25s with Paddy Power for the Albert Bartlett Novices' Hurdle at Cheltenham.
Mullins said: "He's improving all the time.
"He's already shown good form at Cheltenham and we'll have to consider the Albert Bartlett. We'll have a chat with the owners and see what they want to do."
Mullins predicts a bright future for Annie Power (1-3) after she followed up a debut jumps success in the Kilsheelan Mares Hurdle.
Despite being untidy at the final flight, Annie Power was untroubled to triumph by six and a half lengths on the bridle.
She is now unbeaten in five and has claimed a bumper and two hurdles since being bought out of Jim Bolger's yard.
"She was taking on more experienced mares today and did it well," said the County Carlow handler.
"I think she handles all types of ground and that's good experience for her jumping around at that speed.
"The last was the only mistake she made and she'll learn a lot from that.
"She's entered at Cheltenham but I think we'll probably keep her at home - there's a good mares race at Fairyhouse.
"We think quite a lot of her and she could be anything. She could also be a really good chasing mare in time."
Sarabad (7-4 joint-favourite) struck first for Mullins and Walsh with a 29-length romp in the Surehaul Race Day Maiden Hurdle.
"Ruby made it a test of stamina and that seems to be what he wants. I wouldn't be afraid to go two and a half or three miles with him," said Mullins.
Cadspeed had every chance but could not continue the Mullins and Walsh hot streak when having to settle for minor honours behind the Tony Martin-trained and Davy Russell-ridden Savello (3-1) and Page Turner in the Kilmolash Beginners' Chase.
