I've finally decided to get a switch rod. I was all set on buying a 7wt Echo SR, until I was offered a good deal on a 7wt Echo3 switch. With the discount, cost on a new Echo3 is still more than the SR. The primary use for this rod will be swinging for summerruns and I already have an Ambush line for it. Thoughts? Experiences? Does one cast single handed better than the other?
