Hiku has always been a riddle to me that has been very difficult to solve. I like having him around because he truly can play pretty much any spot in the backline, but his best spot (imo) is fullback, but he's always behind Snake, and I do think Tommy Turbo is a much better option long term as well. So unfortunately this has meant (and will mean), Hiku never truly gets the spot he's best suited to.
So I do think this is one of those bite the bullet decisions which can be hard to take, but is probably in the best interest of both parties.
