Who has built a Batson Eternity2 9' 6wt, or even a 7wt or 5 wt.

I am looking for a great line match. Rio Tech Trout is good for dries, but not so great for other applications. I did not like SA MPX. An older SA Textured Trout is OK. Rio Avid Trout OK. Anyone have a line they love on Eternity2?

Have you CCS measured the rod? All the Eternities I've built are a little above the nominal line weight designation. I've only built Eternities 8 and above. I use an Orvis Bonefish line on my 8, but it's for salt/warm water. It's a nice line for it's intended use, but tends to coil some in cooler MI when I'm practicing.

For 6’s and under, I just go with a DT line anymore. Longer leader for dries.
The line specialization has gone nuts and with the prices it is tough to experiment. If you have a good shop that will let you test cast lines, go for it. I use SA frequency or 406 fly lines.

I kind of miss Phil E. when I see threads like this.

If you want a non specialized line that helps you cast well and far, when necessary, try a Royal Wulff Triangle Taper, it does have a downside however, due to the design of a long continuous taper, it is very light in the first 10-15 ft., the lightest out there that I have experienced, this decreases its efficiency when fishing in real close like pocket waters. Need to rollcast well? This is the line for you.

I did not perform CCS but, to your point, the E2s reputation is to like an above normal line weight, which is why I tried a several year old Rio Avid Trout, which I think comes in at 1/2 to a full line size heavy. It's OK.. Now they have Avid Trout Gold and Grand, based on those tapers. I even asked Batson and they said go over standard with E2. I'm wrapping up an Epic 690G blank so it will be interesting to compare it to the E2. I have high hopes for the Epic, as it only gets rave reviews.

I fish build and fish Eterenty 2's and prefer Rio gold or grand depending upon casting distance needed. The Grand for longer casts.
