Bowles admits that his boys are gunning for revenge
Under-19 Inter-Provincial champions Ulster make a couple of changes for what will probably be the title decider against Leinster at Deramore Park this afternoon (2.30pm).
The home team defeated Connacht 24-17 while Leinster gained a 19-10 victory over Munster last weekend.
Wallace High's Andrew Cardosi, who came on as a replacement last Saturday and scored a vital try, will be at full-back for Angus McCartney.
Matthew Hooks comes on to the bench as a backs replacement and Matthew McKinney replaces Duncan Maguire on the bench.
Coach Clive Bowles knows Leinster will be strong.
"They have a strong structure of boys coming through who have been given a lot of professional training," he said.
"Our squad has worked hard throughout the summer and are keen to avenge last season's 30-14 defeat at Schoolboy level."
Ulster Schools overwhelmed Connacht 53-0 at the Sportsground last weekend but they should not read too much into that result, especially as they have to face the champions Leinster at St Mary's.
In that victory, No 8 Zach Jordan sustained a leg injury and is replaced by Saul Herdman to give Methody their fifth representative on the team. On Wednesday, Munster recorded a 24-3 win over Connacht.
Following their 27-7 success over Connacht, Ulster under-20s make two changes for the visit of Leinster to the Kingspan (4.00pm) with Angelo Marica and Ross Todd coming in.
Ulster under-18s face Leinster at Navan and Ulster Women take on Connacht at the Kingspan.
