One of our sponsors on here, Curtis, has the "Litewire Hooker jigs" which wil usually staighted out if you hang up. I plan to try tightlining in a lake filled with brush and stump this spring and all my rods will have his jigs on them, cause I know I will get hung up. Once I learn the terrain I am hoping I can set the jigs to run just above the brush, but I know I am gonna hang up some til I get it figured out.
Most of my fishing has been on a big reservoir which has consistent depth and not a lot of brush, so I just drop to the bottom and reel up about a foot or two and seldom hang up.
