Ive been thinking about making some carolina ready rigs like the brass ones but using tungsten. I used the carolina keepers but they slide down on my line.

 

anybody have any advice in the keepers 

You can add a second keeper to stop the weight from sliding down

I'd ditch the Carolina keepers in favor of two or three bobber-stoppers.  Easier on the line.

Main line to swivel. Weight can't get past the swivel, and no "keepers" needed.
