This is one of those builds.. I love this rod so much I ordered myself a blank right away. The lightest, "skinniest" 5wt. ever made by Sage. Very smooth, lively, accurate. A medium fast action rod (not even close to slow) with a progressive taper but amazing recovery speed. Can be a good all around rod but it will excel on dry flies and those trick casts that I like. I like to cast it with a lighter line (#4 or even #3) because I like quicker action (not stiff rods). The Circa is a very special rod, feels ultralight in the hand, has a very small diameter, similar to the TXL series wich is pretty amazing for a rod of this size. I didn't go much different than the factory build, except the handle and a slightly lighter silk thread. I did use smaller guides that the factory build because it feels more responsive. This rod may be the perfect trout rod for those who like medium fast action rods. Rod is built for a friend in Norway. Thanks for looking!
