usually happens on the cast when the hook link is to long and a cheap non coated braid is used,i would use the most expensive coated braid you can afford and just strip the outer coating off at the end for your knotless knot to the hook,the rest of the link will now stay slightly stiff,keep them short is the key imo and should easily overcome the problems your getting
