Hey Steve, first off, where did you get 18 pound cannonballs??? I would love to get my hands on a few of those!
What you're experiencing is a boom pulley stack on your spool.
As you troll, the boom pulley swings aft with the wire and causes an uneven spool, leading to the "jump and kink" in the spool.
You can easily correct this by utilizing your boom mounted ball hook as a level wind.
With the opening of the hook pointing forward, tighten the hook mounting collar to ride the wire so it hits the middle of the spool and you're in business!!!
