I read alot of people looking for a varible depth setup. I use a pole float with a bead slightly larger than you line. If you double your line in a simple knot, and run a peice of dental floss thought the loop and pull tight. You end-up with a bobberstop that you can cast though the eye-lets of your pole. I normally set them at 5-10ft deep without a problem casting. Pull the floss and you can simply pull the knot out. If I'm not mistaken, this is the easiest variable bobber stop out there. With a bead above the bobber and the hook set so it doen't cross over the top of the bobber(the helicopter effect). A leathal rig for any fish. Let me know what you think!
