Ok so with the taxes coming up I will be buying the 4wt switch rod from echo. Im debating on what line to get and need you guys help considering a vast majority of you are more knowledgeable on the subject. Im looking at the 270gr window. With the versitip You get the 4 tips. With the Airflo I will buy the entire lineup of trout polyleaders in 10ft. So which one should I get and why?
