I have an 8wt Sage xi3 that I bought in spring of 2010, literally about three weeks before I found out I was moving away from the ocean to PA trout country. Oh well. Anyways, the rod's a beast and although I've only gotten to fish the salt twice this year, I love casting that rod. On the plus side at this rate it'll last a lifetime.
When I was back in MA visiting my folks, my Dad and I cast the BVK, Orvis Access and Sage Flight in a 9 wt. The BVK clearly stood out as the winner for us. The Access stood out too, for sucking.
I still like my xi3 better, but in no way is it 3x better.
As for the NRX, what's with the teal wraps? I've never cast a Loomis rod. I hear many good things, but is it so hard to make one that looks good too?
