With Decoy single hooks, the rig determines the shape you need. A replacement hook on a spoon connects differently from a dropshot hook or a hook mounted in the top of a softbait. Compare eye and bend first, then the size code.
Large eye, dropshot or a 60° eye?
The Finesse Single32 has an extra-large eye for applications including split rings and articulated rigs. The Worm23 Body Hook has a wide bend and slightly upturned eye; the Shot Rig Worm10 is intended for applications including nose-hooked dropshot presentations. The JIG53F 60° Limerick-F instead uses a flat eye at 60° for techniques such as Mid Strolling.
Barbless is a separate choice
The Area Hook Type III AH-3 is barbless and intended for small spoons and hardbaits in trout area fishing. That feature does not automatically apply to every hook here. With a replacement hook, also check eye orientation and whether it moves freely on the split ring.
