Thank you for all the help. Here in Denmark we don't really have much Hardy stuff. Echo is limited. Z-axis is not sold in stores anymore except for double hand rods. But maby I can find it used somewhere.
I went to a lawn today with my One 691 to do a final decision. I started with shooting head 16gram. It didn't work for me. Then a 6 Rio Gold, couldn't feel the rod at all. Finally I tried with a 7 Zpey Ultimo and now I started to feel the rod and the cast was so easy, not just the distance, but also in close. It was so much fun to practice hitting targets (leafs on the lawn).
This opened a new thought for me, that it does matter what line you put on a rod.
But this is still overlined with a 7wt line instead of 6. I don't know how it will feel with the same line in a 6wt. And this put me on a disadvantage if I want a versatile rod that I can bring to a river and still have fun.
I'm not familiar with river fishing in general. As long as I have been fly fishing I have hunted seatrout in saltwater. On rare occasions I have been on a river. What my plans are for river fishing is nymphing and dry fly, maby streamers.
Brown trouts are not as big as seatrout, so a too stiff rod will kill all the fun. Many rivers in Denmark is just small stream fishing with a few large ones. We certainly can't compete with you guys in America.
I don't know, this is just some thoughts. Thank you for helping
