Yes I think the new technology is coming through again in these rods. Sage calls there's"Generation 5 Graphite" Maybe its hype. But the new xi2 is aboyt .7oz less wt than the rplxi in the 10 wt.
It does feel very light-surprisingly so-. I did notice that the rod didnt roll cast well unless you only had a short amount of line out. But the speed and tight loops well make up for that in my mind.
