Ballymena's speedy winger Johnny Rosborough ran in three first half tries for Ulster Under-19's in their 36-7 win at North Wales.
Gareth Millar converted all three to take a 21-7 interval advantage and after that they never looked back.
"We had further tries from Conal Boomer, Paddy Wright and Ryan Spence but our dominance of the second half should probably have produced more," commented Ulster Manager Clive Bowles.
Meanwhile, the Under-20s suffered their first defeat of the season but put up a determined performance against a strong London Irish Academy XV at Sunbury.
Irish managed three tries all from their pack while Ulster contributed two team effort scores.
Conor Young and Andrew McGrath were the scorers while Jack Milligan kicked two penalties and a conversion and Josh Bingham two penalties. Manager Terry McMaster said: "It was a pleasing result. We were up against very physical and aggressive opponents and although we narrowly lost it was great preparation for the Connacht game."
Ulster Schools, following their 20-7 success at London Irish, travel to Troon to face Glasgow and District. This is their final outing before meeting Connacht next Saturday.
