Ballynahinch remain the only team in the AIB League to still boast a 100% record, five weekends into this season's campaign.
The County Down side scored a thumping 52-10 victory over Sunday's Well at Ballymacarn Park on Saturday, with their total including seven converted tries.
'Hinch made it five wins out of five with winger Aaron Ferris bagging a hat-trick of tries, and centres Stewart Megaw and David Harris, scrum half Adam Bartholomew and prop Ricky Orr were also on target. Number 10 Daniel Soper, who also kicked a penalty, added five conversions with replacement Peter Connell converting twice.
'Hinch are four points clear of Instonians at the top of an Ulster-dominated table.
Against Portadown, prop Chris Schofield, hooker Wilbur Leacock, lock Kenny Morton and flanker Adam Telford emphasised Instonians' forward dominance as they all touched down in a 34-11 win for Inst.
Ulster Under-20 out-half Owen McMurray added four conversions and two penalties to complete the scoring at Chambers Park.
Banbridge have jumped from tenth to fifth place in the standings on the back of a 39-15 win over City of Derry. Centre Gareth Martin took his league try tally to five at Rifle Park with a well-taken brace of scores, while lock Simon McKinstry, flanker Gareth Bell and full-back Stuart Wilson also grabbed tries for the Down outfit, who lost Tyrone Howe early on to a knee ligament injury.
Corinthians won their Galway duel with Connemara 15-3, while Nenagh Ormond and Ards fought out a 20-20 draw down in Tipperary.
Old Wesley squeezed past Queen's at Dub Lane, winning 10-8 thanks to a try from their star back Brian Doherty - that was his fourth of the campaign - and five points from the boot of David Smyth.
Wanderers kept up their run at the business end of the table with a 24-10 defeat of play-off rivals Bruff at Merrion Road - big flanker Kolo Kiripati and centre James Ferris both managed to cross the Limerick side's whitewash.
Meanwhile, Rainey Old Boys, only in their first season in the senior ranks, look like challenging for a play-off spot, even at this early stage. The men from Magherafelt earned their fourth win in five league games with a 33-15 success away to Waterpark.
Hooker Damien Campbell (2) and winger James McBride were amongst the try scorers for Rainey.
