I'm re-phrasing my question. I'm getting a rio scandi body for my z-axis 8110, I'm thinking either the 7/8 @ 375 grains or the #8 @ 400 grains, Im planning on fishing mostly sink tips, sustained anchor, and traditional spey flies & streamers. Do any of you have experience with this rod line combo? Or any input as to which line may work better than the other? Thanks.
