I have seen these but, never bought them. How deep do they run on the retrieve in the water column?, and can you burn them while still staying upright and not running all Helter Skelter?

I've used them with some success - - - I've never really burned them, but they seem to react just like a normal Rat-L-Trap once the action is initiated.   I got them for "finesse" fishing flats.......letting the lure sit on top and then pulling it under for a few feet, etc.....

try Lucky Craft LV-0  

You can even get suspending lipless cranks.
