i agree with skate,there is no "definite" answer here.you need to have both.another thing to keep in mind is how you present each one,whether its on a rigger,wire,or copper.we usually split the boat with spinnies on one side and paddles on the other and let the fish tell you what they want,but like skate said,sometimes its neither and they want spoons,which happened quite abit last year.another thing to consider is your trolling speed.i believe spinnies can handle a higher trolling speed then paddles,so if you have spoons out and your speed is up abit,then you may want spinnies out instead of paddles.what ever you have out needs to "look good" in the water.and like what was stated above,its not an inexpensive sport!!!!
