Grubs are measured when their tails are straight. They appear smaller because of the curl in their tail. The 3.5″ Micro Power Grub is the perfect teaser to use on a 3/0 or 4/0 standalone hook or behind a teaser fly. We also use this Micro Power Grub on our smaller bucktails, 1/2 to 1oz. The MicroPower Grub is hardier and fatter than most grubs its size.
