Mick - I agree with Sami, that a 6000/8000 size Shimano would be the winning ticket.... I fish a 6000FA with an 8000FA spool on my OR STK76 which is a similar rod ( Sami correct me if I'm wrong, but they are fairly close right? )
Try PM Nick Bowles of Ocean Active, his KGS has caught more big fish than I've had hot dinners! I think he fishes an Accurate SR12 if I'm not mistaken....
