The Y-S81 Trebles from Decoy are stronger than standard treble hooks but no thicker in the wire.
If you are using a powerful rod with braid on your reel, or if you are fishing for hard fighting fish, then you should consider stepping up to the Y-S81.
Another great feature is the "split ring friendly" hook eye. The eye has a thinner part that lets you insert a split ring very easily.
