Whats the best way to rig/fish these? They look similar to a senko so Im assuming they're done the same way. I just wanted to make sure.

Shakyhead, weightless, wacky rigged, T-rigged, C-rigged, it's a finesse worm so pretty much anyway you'd fish a trick worm/straight finesse worm.

those worms are some excellent flick shake/shaky head worms.

Shaky head or Carolina rig. They float, so these two are good rigs to take advantage of that.

My personal favorite shakeyhead worm. Plenty of colors, cheap, available everywhere, and the plastic is a good marriage of durability/action.
