If you decide to go for the Kong swivel wouldn't worry about the links. I have a Rocna and the Kong is supposed to be much better with side loads than the Force 4 type so there is virtually no chance of any problem. Alternatively, try the links without any swivel and see if your Rocna comes up the right way. If it does you might not need the swivel at all.

If you look at the second link to my website given above you will see the reason why the extra links are needed with a Kong in conjunction with any anchor with a plate shank. Before I fitted the extra links there were many occasions when my anchor was recovered with the Kong in the wedged position.
