Hook Recommendation

Bought these to throw in the surf .  Going to change out the trebles to a single , so I`m looking for recommendations .

Also , I`m thinking , going to add a split ring onto the lure ? ,I would be interested to see opinions for a direct  tie to the main line or swivels types etc etc ..what would you  do /use ?  ..you know for S n`G`s

I've seen people swap out those trebles for Ownew single in-line hooks similar to these but maybe 3x or 4x.   http://www.tacklewarehouse.com/Owner_Single_Replacement_Hook_X_Strong/descpage-OSRH.html
