Admittedly, the Ospreys will have to guard against complacency as the North produced their best performance of the season last weekend - going down 18-12 to a strong Dragons side.
Iolo Evans and Andrew Oakden scored on that occasion and both players are included in a side that sees goal-kicker Alex Schwarz on the bench for the first time this season.
The North Wales Under 18s have found things particularly tough this term - in three games this season they have conceded 26 tries and 155 points.
Still, home advantage might count for something against an Ospreys side who went down 23-13 to the Blues last time out.
