Find a rubber cap (sometimes called a butt plug) They actually sell them pre set up but the homemade ones are cheaper and better.

the problem is you have to find the long ones that are about 2 inches long. next take 2 one oz sinkers place hole up (they well ballence) smack with a hammer until they fit the diameter of the plug, place it on the butt of your pole. it makes the tip light and your sence off feel well inprove greatly....DJ
