My take on it for what its worth:
I would be happy with King, from what I have seen he looks a solid SL player.
I would keep Arona if at all possible but if he (his agent) is asking too much or he has a big offer elsewhere then I would be disappointed to see him go but would understand why the club wouldn't break the bank for him.
Finn is a tough one, he has been great for us since he signed but the past few games he has played he has looked past it but is that due to him carrying an injury? The guy has a great rugby brain and I would be looking at keeping him at the club possibly in a player coach role if the price is right.
Kirmond i did think previousley that his performances were declining but he has been great in the past couple of games and also he is great around the club. I think I would offer him another year.
