That was my interpretation as well when I had read those posts prior to purchasing. But handling the rod myself, I guess I am second guessing what I read. No way I would think this is a 5wt rod, ever. But, I'm going to go and try it out this weekend and see what I think.
And there were a few others about deep flexing and working well as a fly rod, but seemed maybe two people only had experience with the rod.
It was this post and board member that mentioned use with a 5wt. I downloaded the picture to be sure it was the fly/spin rod that he acquired.viewtopic.php?f=2&t=10444&p=65906&hilit=Fullflex#p65906
And then this post from wb4tjh : "have the very last 7 foot, 4 piece Orvis glass fullflex spin/fly pack rod sold. I bought it in the late 80s thru a friend of mine in Memphis who owned the local Orvis Shop. He called the factory and they went out in the showroom and got what they told him was the last one they had. It sure is a sweet casting 5/6 weight. I've taken everything from little trout and bluegill to a 10 pound redfish here in Sarasota Bay on it. It really bends way down into the corks. It throws a long line with a spinning reel too. You can heave a weighted jig what seems like a mile with the fully loading rod."
I agree with the other comments that fly/spin tends to be a compromise, other than maybe a Phillipson fox combo that had some great comments. I was just hoping to take this for the kids who try to fly fish but will resort to spin fishing.
Having the catalog and comparing with fly only version would be ideal situation here.
But, for a new old stock, worth a shot.
