Phil,
During the spawn
my favorite way to fish the worm is by a technique called flipping..You quietly sneak up on the bass and drop it right on them in heavy cover..The rigs I sent you is what I use.Here is a video I found demonstrating the flipping technique..You simply let the worm hit the bottom and bounce it slowly a couple times...you drop it in every hole around...Since your in heavy cover you must have a medium heavy rod and heavier line because you want them out of the soup quickly.
I love this technique best..
I use 20 pound Power Pro...The diameter is skinny and when used with a Palomar knot nearly impossible to break..I've fished 2 seasons so far with it.
In Feb. this year I got 20 in one outing doing this .
