That's funny and explains style I guess cause I replaced my Gold for the SS. BUT, I went with the GPX on my 5 weight and up and yes on my BIIx.
But the Trout in a 4 which is glass, bamboo, Trout Bum, Superfine, and JWF so all full to medium flex.
I don't know, Gold just didn't do it for me....but I know everyone else likes it.
The Rio Grand made more sense to me, for big flies.
