We just completed testing the new Airflo Skagit Switch Lines and the results are very impressive. We were able to easily cast a 13ft. sinktip of T-20 on an 8wt.-11ft. Switch Rod! Previously, we had problems doing this on a 7/8wt.-13’6″ Spey Rod. The new Switch rods and Switch lines are amazing. Very little effort is required, they can operate in tight spaces and casting up to 100 ft. is comfortable.
