RBAI will guard against complacency on Saturday morning at Osbourne Park when they face Royal School, Armagh (11am).
Having cruised past Regent House in the third round, the Belfast chaps will find the boys from Co Armagh a sterner test.
Team coaches, Dan Soper and Richard Hedley will prepare their team accordingly.
There is a positive feeling within the Inst squad at the minute that this could be their year to experience Schools’ Cup success!
Team captain, Lewis McNamara, ably assisted by his vice-captain, Michael Mairs, will not allow their players to take anything for granted.
There is an abundance of talent in this Inst squad. Conor Field has represented the Danske Bank Ulster Schools’ team while Michael Lowry is recognised as a very talented outhalf.
They will hope that Lowry will be fit enough to, at least, take his place in the extended squad for this game.
There is strength in depth available to the coaching team.TJ Morris, James Hume, Calum McLaughlin, Jack Conlin and Ben McGavock all bring creativity, pace and power to the Belfast Inst team.
In the Inst pack, Lewis McNamara gets great support from fellow back row players such as Patrick Nicholas and Ethan Harbinson.
Their effectiveness at the breakdown could have a big say in the eventual outcome of this game.
RBAI has a good mixture of youth and experience.
There are winners competing for every position and the starting XV will be keen to ensure their tag as favourites to win this tie are fully justified.
They have lost just once this season to a school team from Ulster. They will want to have that statistic still in place at the end of the game on Saturday.
RS Armagh will be delighted to be seen as outsiders to win. Team coaches, Gareth Beggs and David Dougherty, realise their charges might have been somewhat fortunate to come away from Limavady Grammar with a narrow victory in round three.
However, they did come through and will be going all out to gain a place in the semi-final of this prestigious competition.
The coaches, as well as the players, can call upon the experiences of the redoubtable Kenny Hooks to assist them as they prepare for what will be a challenging encounter.
Kenny had many years with his hands on the helm as he prepared Royal School, Armagh teams to mount successful challenges in the Ulster Schools’ Cup.
Players such as Chris Jennings, Matthew McSorley and their Danske Bank Ulster Schools’ prop, Philip Matthews, have all scored tries in previous rounds.
Their impressive team captain, Michael Thompson, has displayed great game management skills as well as weighing in with some fine kicking skills.
