Yall use the big bull worm much?
I use a Bull Worm all the time, it is probably my preferred c-rig plastic right now and I will throw it on a magnum shakey head as well.
As for the other 10" worms, I use a power worm or Zoom Ol'monster a lot, T-rigged, typically about a 1/2oz tungsten, 6/0 owner twistlock - http://www.tacklewarehouse.com/Owner_TwistLock_Open_Gap_Centering_Pin_Hook/descpage-OTLC.html
- and just slow drag it on the bottom. I typically use the 1/2oz weight to make sure I keep bottom contact. I tend to throw it on points or ledges, not necessarily around heavy cover. If I am around a lot of cover I will stick to something more straight tailed and if I want the 10" size then I will put the bull worm on, I think the big ribbon tails on the other worms will hang up more often and you will have a tailless worm most of the day.
