Since heavy GT popping was introduced, the ideal hook has always been considered to be a heavy (bloody heavy!) treble hook. There have been very few options here outside of the Decoy GT, the Gamakatsu Recorder, the Fisherman KG120 and to a lesser extent, the Owner ST-66. This has now been replaced by the ST-76 which from the little experience I have had with it is a far superior hook.
Exeprienced GT fisherman have all had problems at some time with their trebles, even with these super-strong trebles. It appears that at certain angles where the GT can really exert direct pressure on the hook that they will compromise it.
In the last couple of years, there seems to have been a discernible move by quite a number of GT fisherman to single hooks. Ones which are being used include the incredibly strong owner Jobus, the owner opposite eye S-77 Stingers and a number of guys are now starting to rig up assist hoooks like the Fisherman Sidens or the Owner SJ-51.
Based on my limited experience with singles, I have no doubt they hold better once you are hooked up but I don't know if the percentage of hook-ups is as high. That said, there also appears to be anecdotal evidence that the singles do less damage to the fish.
Looking at it overall, I think I will probably be switching predominately to singles but I will still carry some trebles. Now if only I can make up my mind which singles to use and whether I should be rigging assists instead of the hook directly onto a split ring!
