If the 1/4 ounce has a size 14 hook out of the box, then you can get by with a 12 without messing with the lure’s action. Joes has Mustad trebles right next to the Z-Viber lure selection that are slightly heavier wire than the usual #35647 Mustad treble. 12’s and anything smaller might be tough to find in a brick and mortar store. I checked Netcraft and they don’t show any trebles beyond size 10 in any brand. Try both Barlows and Captain Hooks if you can’t find anything locally.
