I was fishing the drop off into the channel at South Beach with a sink tip and getting hung occasionally with what seemed to be mungy stuff (deep weed?). This was with a new Daichi SW hook with first half hour use. At one point it got hung pretty good and I straightlined it and it came back broken at the bend.
Your point about light wire is interesting. Over about the past ten years of largemouth tourney fishing I have used light wire Owners and Gammis and have never had problems with broken hooks.. Maybe the heavier wire hooks have to be processed differently for chem sharpening. I have had no problems with cheap Eagle Claws on my salt streamers.
