Who to train?

So I'm undecided who to train up. I have one slot for a flanker, and one will go to a youth player due to be promoted in 2 weeks. The third slot is between 3 players:

Notes:

Babel is my best centre and my 6th best player
McLucas is my best front row
Cypher has just been promoted and is due pops in Attack, Defense and Speed (no IGT at the end of season to push him to 14).

Only one slot (9 nets) is up for grabs...
