A vibra tube is my go to bait in a tournament when I cant get a bite on anything else. Blowdowns, shallow brush piles, around stumps, etc. They are great when fished like a regular texas rig.
you just hop em cross the bottom.... i aint never hap any luck on em i ve had few bites..... but for brushpiles where most people throw tubes i like to use a zoom baby brush hog or a 7.5 culprit junebug worm and it never fails me
