Instonians made it six wins out of six and gained a valuable bonus point in a 38-15 win over Nenagh at Shaw's Bridge but stay in second place a point behind Bruff as they also took maximum points at home to Rainey.
After digging deep to beat Queen's and Naas, Inst regained their try scoring form running in six touch downs and coach Clem Boyd was happy with the result.
"I'm delighted to get five points considering what the conditions were before kick off and there was a late pitch inspection," said the former Ulster prop.
"It was a great start and it was something we'd talked about during the week. We'd talked about playing in tight in the opening few minutes into the wind but the guys opened the ball up and must have seen something and full credit to them they came away with tries."
The victory opened up a five point gap over third placed Queen's but Boyd believes it's too early to talk about promotion.
"It's just a matter of taking one game at a time, we have another home game next week against Midleton but after Christmas it is very tough as we have four away games and one at home," says Boyd.
"We start with Banbridge away in January then travel to City of Derry before we have Bruff.
"We're happy to be unbeaten but equally we could be sitting with three wins and three loses as we squeezed a few wins but it's good to see patches of a good performance and hopefully it's a sign of things to come," concluded Boyd.
Winger Adam Telford, centre Michael McKeever and hooker Wilbur Leacock scored tries in the opening 16 minutes.
Kiwi flanker Scott Uren who produced another eye catching performance got the crucial fourth try.
Niall Malone and McKeever's second rounded of the scoring.
Rainey couldn't do their fellow Ulster teams a favour as they slumped to a 31-0 defeat at Bruff.
Queen's maintained the pressure on the leaders with a 17-9 win in Cork against Midleton.
Michael Barker, Ian Whitten and Michael Hooks got the Students' tries.
City of Derry were plunged further into relegation trouble losing 15-5 at home to Co Carlow will Ards and Banbridge's games fell victim to the weather.
