How long a worm a Bass would Bite???

Two (2) years of testing...Not in stock ponds..not in Mexico, but in local lakes where the average fishermen and women fish, and as the saying goes, "in our own back yard" the good ole USA.  Started with a 2 foot worm, results xxx.  21"worm, results xxx 19" xxx ...18"xxx. Finally  the ultimate length???

One of the World''s   LONGEST SOFT PLASTIC (FISHABLE) WORM    COMMING SOON,  GOT-ZILLA 17 INCHES OF LETHAL BASS CATCH POWER.  SUPREME BAIT FOR BIG BASS.  

 Also not the longest but by far one of the deadliest big bass worms you''ll ever tie on  The XL 14 INCH RIBBON TAIL WORM. 
 Wt. of bass caught: 6lb 8lb 9lb and sme over 10lbs  Not only do we have pictures to prove it !  We have films of catching them.
