Discipline is going to be key for Ulster as they attempt to record what would only be their second away win of their campaign at Cardiff on Saturday night.
Matt Williams' men have received yellow cards in their last three games and have also been at the wrong end of penalty counts during the two defeats to Munster and Neath/Swansea Ospreys as well as the patchy victory over Connacht.
Travelling to face a Blues side who will be desperate to keep their faint Magners League title hopes alive, Ulster cannot afford to lose the penalty count if they are to record their first win in Wales since September 2006.
The Ulster coach however feels his side were dealt a tough hand during the last three games.
He made a point of calling on the referee to give his side a fair crack of the whip in the run-up to the Connacht game.
"Our scrum was good and I was very confused at our penalties at the scrum," said Williams. "Very confused to say the least. It would have been a very difficult to lose the game on those sort of penalties."
Brian O'Driscoll could return to action for leaders Leinster in Friday night's Magners League clash against Edinburgh at Murrayfield, he was in extended panel for last weekend's win over Munster but he did not make the match day squad.
A bonus-point win will virtually guarantee Leinster the title.
Meanwhile, building on the success of the 2007 Guinness Carrick Sevens, the Lombard Ladies 10s will again take place with 12 teams participating.
Five Ulster sides will be taking part with Cooke attempting to retain the cup.
The ever improving University of Ulster Jordanstown will be wanting to mount a strong challenge, Carrickfergus will be looking to get the home support behind, while newcomers City of Derry will be keen to make a mark, along with the students from Queens.
Of the touring sides taking part, Pontyclun Falcons will want to improve on their semi-final placing from last year but in addition will be keen to be the leading Welsh side ahead of Cowbridge and Merched Dollegallau.
Wimbledon, affectionately known, as the "Wombles" who are bringing two teams, will be looking to impress but they may find stiff opposition from Leeds Metropolitan University and Hertford.
The weekend will start at on Friday, May 2, kick-off 6pm, with the Kukri Sportswear Under-20s with 12 teams involved.
