Joining the love-in a little late, but I have to agree the Barrio is easily the best switch line I've used. It has the right weight and distribution to do what it is meant to do i.e. Doublehanded Spey and singlehanded overhead cast. I've never fished with the OPs make of rod, but I think the suggestion to contact Mike Barrio is a good one. A small heads up. Barrio Lines need to be looped at both ends. Personally, I've more faith in a whipped Roman Moser loop coping fine with the loop to loop connection of a flurocarbon leader than a welded loop. However, if you are not so keen on that, they have just introduced a custom welded loop service.
