Imakatsu HUDDLE FLY was designed as an ultimate tournament bait that is necessary when the final one fish is needed under the tough condition.  The gap in the huddle tail creates a strong push against the weak silhouette.  The little huddle-tail is seemingly motionless.  But, if you look closely at the point, you can see it moving finely.  The movement is like the tail of a real small fish.  It can be used on any rigs, including drop shot rigs, no-sinker rigs, and Carolina rigs.  I-motion method with small offset hook is a secret.
