Most of the time, fish feed on distressed or distracted prey.  Total
opportunist, they love an easy meal.  Injured prey give out sonic vibrations
delivered through the tail that trigger a natural feeding reaction from the
closest predator.   Just drop a injured minnow or bream under a dock and
see what happens. A bass may come from 20 ft away to eat this one bream,
when it may have been closer to other healthy swimming prey. Why?  Pure
& simple the bass pickedup on the distress vibratory pattern first.  

Certainly a bass uses all its sensory to survive. Hearing, sight, and smell.  
What triggers a strike the majority of the time is the secret to a great lure.
Bass have an inner ear and outer ear with sensory canals along it's lateral
line.  Sound and vibration are used to track, kill, and eat its prey.  Sight is a
last minute "lock on" sensory for this entire process.  If sight was the first
line of use, how can fish feed in total darkness?  Vibration first,  always.

The Wedgetail delivers 95% of its vibratory energy at the tail portion.  It's vibration is exactly
that of a
fleeing or distressed prey.  It's secret to success is the shape of the tail.  When
retrieved slow, medium, or fast the tail is kicking and creating a distress vibratory pattern...
A constant fish call, if you will.
The Wedgetail is a simple design, yet holds the secret to why fish strike lures.  The
Wedgetail is designed on one simple principal.  
Vibration is a key trigger mechanism that
causes a fish to strike any lure.  
Think about it,  a fish delivers all of its energy through its
tail.   All other fins are for balance, guidance, or orientation to it's environment.
