In situations where you've narrowed down the target to a particular kind fish, we recommend using Gorensha Series hooks for the particular type. (When tachiuo [largehead hairtail], sawara [Spanish mackerel], or other sharp-toothed fish are present, please use Gorensha hooks that have Zylon assist lines.) When targeting blue-skinned fish, if fish ranging from hamachi (young yellowtail) to warasa (middle-size yellowtail) or mejiro (Japanese white-eye) are the main target, use warasa hooks; if warasa through buri (adult yellowtail) class fish are the main target, use buri hooks. Double hooks distribute force, so some effort is needed to set them, but they hold well. This greater distribution of force compared to a single hook makes for correspondingly less chance of the target throwing the hook. They also offer the advantage of enabling quick setup. Give your imagination full play to come up with the best combinations matches to the characteristics and behavior of each kind of fish you want to catch.
