Don't think u really need a weight. I really think your problem is getting your rod tips down. Next time u reel your crank up, feel the difference in tension it makes when you got your rod tip up, down, and then down and to your side. In my opinion it runs best down and to the side. Figure out how to get all your poles running this way and you won't have to worry with weights and such. I am by no means a pro cranker but this I learned pretty quickly and began catching lots of fish when I got them down and out the side.
