I use the .250 diameter balls pushed into the black tubing. I use a cheap twisted swivle, and cut off the barrel portion. Slide a cheap swivel on the main line and clip onto the weight, tie on on of Bob's quality swivles and snap onto a pretied leader with a quality barrel swivle on it.

All of the tying and weight making is done prior to fishing.

You only have to tie one knot to put on a new rig. If you break off the leader, you just snap on a new one.

The othere advantage is that everyone on the boat can have the same weight on when boondogging, keep the tangle factor down.
