I don't own a "One" yet but I have cast several of them. I think we have sold a couple so far. I was impressed, especially with the 6 wt and a Rio Smallmouth Line on it casting on grass. Personally I was impressed with accuracy but I didn't have any other brands out there that day to compare to. I am meeting with the Sage sales rep again tomorrow so I'll probably make some comparisons if time allows. I fished all day today with a avid 26 year old guide. He wore me out on the lake. I hope my arm is up to the challenge tomorrow.
