A direct replacement for Lauititi (a game-breaking forward) would be nice. A world class centre would be an advantage for any SL side and a world class 9 would also be lovely. However, the above are probably not available, and I only favour recruitment if it enhances what you have, not just recruitment for recruitment's sake.
I'm not up for backing youth at all costs, to the extent of not bringing in the right quality from outside, but I'd definitely rather back youth next year than just bring in any old rubbish for the sake of filling up the salary cap.
