A good worm fisherman I knew years ago told me he changed plastic worms according to water temp. Early season- only straight tail styles, less action. Late Spring, introduce curly tail plastics. Summer, Warm water, everything. Curly, Ribbontail, and large plastic worms. Fall, most styles work well. Cold water, end of season, back to straight tail styles. He was successful by choosing plastic worms this way. The important time for him was early spring and late in the year, when he liked a straight tail worm the best. Overall, this has worked out for me too. Has anyone else chosen plastic worms based on water temps?
