US, you have to use a bullet weight for plastics worms if you are having problems getting it out far enough. Also, go with the senkos, they are super easy to fish. The action happens when you simply cast the bait, once it hits bottom, all you have to do is tip the rod a bit for the worm to go back into action.
The senkos are great if you are casting is heavy cover or weeds, you just have to Texas rig them. You can go with the wacky rig in less vegetated waters.
