Instonians, the new favourites to win the Millar, McCall, Wylie Junior Cup following the elimination of holders Ballynahinch II, will still need to be at their best to overcome Enniskillen in the semi-final at Shaw's Bridge.
"This tie will be a battle up front and that's where it will be won" said Inst director of rugby Ken Keane.
"The Enniskillen pack destroyed Ballymena II in the last round so we know we face a formidable task.
"Fortunately we welcome back both Rory McCorry at No 8 and Alan Whitten so our pack will be at full strength. In the backs Robbie Kirk plays at full-back for Ben Scott and Jack Finlay returns on the wing."
Inst are still undefeated after seven Qualifying 1 fixtures and are a much superior team to the one that was relegated from the AIL last season.
Enniskillen's record in Q2 is disappointing with three wins from five outings and although they gained plenty of confidence after that narrow 24-19 success over Ballymena they face an uphill task, especially in Belfast.
The other semi-final is between Ballyclare and Omagh who invariably have close contests. Last season the east Antim men just pipped Omagh for promotion to Q1.
Ballyclare are more than holding their own in the top section with five wins from seven games, but their ambition is to finish in the top four and qualify for the All Ireland Junior Cup.
Omagh start without flanker Dean Porter who suffered an ankle injury, but despite having to travel, their director of rugby, Phil Marshall, said: "We have every respect for them but certainly don't fear them."
