Take a bow, Callum Black.
After years as a willing member of the cast, unsung and, like so many of his breed, often unseen, the Ulster loosehead finished the Warriors' home match in a position he had not occupied before - as the headline act of the weekend.
American-born, English-reared and Irish qualified, Black had not managed a try in 99 matches for his grandfather's native province spread over five years but then the whole point about his specific craft is to secure the ball for others to do the scoring.
How wonderful, therefore, that on his 100th match he should do the job if not quite all by himself that at the end of a collective shove grand enough to embroider the milestone not just with any old try but the one which ultimately ensured Ulster squeezed home 13-10.
The result ensured that the champions went home with a losing bonus point, a few peanuts compared to when they last turned up in Belfast, for last year's GUINNESS PRO12 Final, and flew back to Glasgow with the whole caboodle.
Black's try, delivered in the finest traditions of the Front Row Union from close range, doubled his career total in one fell swoop. Contrary to popular belief, he had scored before, not in the GUINNESS PRO12, of course, but during a previous life in the English Premiership.
It came roughly halfway through a four-year stretch with Worcester Warriors, against Harlequins in October 2009 when the man himself still had a full head of hair. He now has two - tries not hairs - in a career total of 130 matches plus two for Emerging Ireland.
As strike rates go, it may not be much to shout about but, by front row standards, it compares more than favourably with a few distinguished figures in the same position.
It took Nicolas Mas, for example, some 80 Tests to score his first, and only try for France. Jason Leonard, arguably the most durable prop of his generation, stood the test of time for more than 450 matches. His tries averaged one in every 90 appearances.
A graduate of the productive Hartpury College academy in Gloucester, Black is in his fifth season with Ulster, having arrived there in the summer of 2011 via Washington DC, Bristol and Worcester.
His try, a fortnight before turning 30, ensured Ulster reclaimed pole position from Connacht 24 hours after their western neighbours seized all five points from the Dragons at Rodney Parade. Try-scoring props appear to be all the rage.
Denis Buckley and Rodney Ah You accounted for 50 per cent of Connacht's tries on their last appearance in Galway, a five-pointer against the Scarlets. Benetton Treviso's long overdue first win of the season, achieved at the expense of the in-form Blues, owed much to the collective effort of their pack as spearheaded by the front row.
Alberto De Marchi, Luca Bigi and Simone Ferrari can claim collective credit for the penalty try which ultimately proved decisive in their 13-7 home victory, their first since they played host to Wales' capital region almost exactly twelve months ago.
Even those props who somehow avoided indulging in the glory of scoring still made news over the last few days. Gethin Jenkins, ploughing on after his 121st international for Wales, has renewed his contract at the Blues for another season at least which will take him well into his 37th year.
Another much younger Welsh prop, Rhodri Jones, first capped by Wales four years ago at the age of 20, has agreed to the shortest transfer of the year hitherto, from Llanelli to Swansea and swop the Scarlets for the Ospreys.
Now that they are up and running, Treviso stay at home with the chance of making it two in a row against another Welsh opponent, the Dragons, on Friday night. Ospreys, their play-off hopes revived by Sunday's victory over Munster in Cork, are also in Friday night action, back home in Swansea against Edinburgh.
The Scots have already suffered more than enough anguish in south Wales for one season. Having surrendered their winning run in Cardiff at the end of last month, they were within sight of a priceless win at the Parc y Scarlets last weekend only to have it wrenched from them.
Aled Thomas' decisive penalty denied Edinburgh a return to the top four, ensuring the Scarlets beat them to it. The Liberty Stadium, therefore, is crucial to their play-off ambitions against opponents reinforced by the release from Six Nations duty of a Welsh quartet - Dan Lydiate, Paul James, Aaron Jarvis and James King.
Warriors-Munster, last year's GUINNESS PRO12 Finalists, promises another collision mighty enough to change the landscape immediately beneath the current top four. Leinster, one point behind Ulster and Connacht but with a game in hand, appear at the BT Sport Cardiff Arms Park on Saturday against a Blues team strengthened by the return from Wales duty of seven players - Tom James, Gareth Anscombe, Alex Cuthbert, Cory Allen, Lloyd Williams, Josh Turnbull and Kristian Dacey.
Connacht, with successive fixtures against all three Irish rivals looming ever larger on the horizon post-Six Nations, make their first Italian trip of the season aiming for the double over Zebre whom they overwhelmed 34-15 in Galway last October.
The biggest match of Round 15 features first against fourth - Ulster against Scarlets in Belfast on Sunday. For Wales' leading contenders to a title they won for the only time twelve years ago, it promises to be the acid test of their ability to go the distance.
Form, never easy to gauge at the best of times, let alone during the Six Nations, is a tricky business. Points gained over the last three matches, from a maximum of 15, gives some sort of guide :
Ulster 13, Connacht 11, Cardiff Blues 10, Leinster 9, Munster 9, Scarlets 8, Edinburgh 6, Dragons 6, Ospreys 6, Zebre 5, Warriors 4, Benetton Treviso 4.
