It is funny to hear how well the Nordic Single has been received with you. When new here it was felt that they were too short in the shank. But yours, and Dana's words count for more than old rumours!
Over here we also have a bunch of excellent "carp" hooks that are very good for this purpose. They shouls be easy to find anywhere in the UK.
I will se if I can send you some. You never got into the Owner ones?
