There were a total of 15 wins across two weekends - more than either their English or French counterparts - with Munster, Leinster, Glasgow Warriors, Cardiff Blues and Edinburgh among the select few yet to be toppled on the continent.
They will be hoping to carry that form back into GUINNESS PRO12 action but something has got to give on Friday night at the RDS.
Matt O'Connor's men are not easily overturned in Dublin but after Edinburgh pulled off a pair of French scalps in the last fortnight, confidence will be flowing through their veins.
Munster visit BT Sport Cardiff Arms Park the following day, seeking to back up their gritty triumph over Saracens - but they haven't beaten the Blues in Cardiff in over five years.
Ospreys, unbeaten in the GUINNESS PRO12 but toppled for the first time this season by Northampton Saints on Saturday, welcome Connacht, while fellow high-flyers Glasgow are visited by Benetton Treviso.
And the weekend's clashes are wrapped up by Zebre's trip to the Scarlets and Ulster's clash with Newport Gwent Dragons - Neil Doak's side with something to prove after a frustrating European break.
All six games will no doubt be an opportunity to spot one or two hidden gems as youngsters across the league will step into the fold to cover for a host of international absentees.
Ospreys head coach Steve Tandy has already labelled hot-shot fly-half Sam Davies as the club's natural successor to points machine Dan Biggar.
