If your heart is set on a 0wt then the only other option is a Dan Craft blank, and build it yourself or have someone build it for you. In a 1wt you have more options.
Elkhorn has a 1wt that is reasonably priced as does TFO.

Both Rods are priced about the same(under $200). The Elkhorn is 7' while the TFO is 6'9". Elkhorn is not as well known as TFO, but they deserve more attention in my opinion. I plan to do business with Elkhorn in the future.

Dave Lewis at Performance Fly Rods makes wonderful custom graphite rods in 1-2-3 weights, in fact any weight you request. He built a 7'0 1-2 weight graphite rod for me a few years ago and It is a quality rod. I just used it today infact catching some nice Bluegills and Crappies, check out his website, real nice guy to deal with. He is located in Harrisburg, Va ......Paul

The Elkhorn 2 wt is really a 2 wt, and a medium action one at that, so it wouldn't surprise me at all if the 1 wt rating is accurate.

Sorry Don, I still cling to the old "stick a line on it and see how it casts" school of thought. You and I have already experienced situations where I feel a rod works better a full line weight lighter than the line you would select. You can tell me it's a heavier rod but if it feels good and will cast the full range of distances for me then I don't care what it's Earned Run Average is ;-)

BTW, I had an interesting experience today. I had been fishing the PY taper most of last week and was casting beautifully. When I was fishing the Blue I was just thinking how smooth the rod is. But then I switched to my Orvis 1 wt and Elkhorn 2 wt for my last two outings. Today I took the PY out again and could barely cast it! It took me a good 30 minutes to slow down and get back in the groove. Initially I was casting so poorly I had to stop and make sure I had the line through all the guides (I did) .

Jerry, that is why this is so much fun. We all have different ideas!

J, I know what you mean. What surprised me is that the PY cane rod is very short at 6'3" and it did allow me a little shorter/faster stroke compared to the Payne taper I had before. It was a little embarrassing :-) I guess you felt the same type of thing going from slightly faster rods back to your Orvis 3 wt huh?

Andy, you're absolutely right. If we all liked the same thing then we wouldn't have 10 Gazillion choices of rods/actions. Plus we've already seen how our tastes in rod actions go back and forth.

Yep...Don, I have had this fight over ERN on another forum, and all I was told is to buy the rod and RATED line, and LEARN TO MAKE IT WORK. I laughed. Rods are designed for a certain line weight, whether the makers truly know what that line weight is or not is not our problem.

Andy, I like what Don just said about casting with the tip versus the whole rod. I'm used to tight loops and higher line-speed which is usually what you get when casting off the tip, where other guys are better at letting the whole rod load and the feel you get from doing that.

And in all fairness I don't understand the whole ERN thing well enough to agree to disagree. For example I don't know how it resolves the two different casting styles above. I if cast a rod from the tip and Don loads the same rod halfway down the blank then how do we know what the optimal flex is?

I should also note that one's particular casting style may not lend itself to achieving the optimum deflection. Overlining sometimes helps by changing the physics, but at a price. Ultrafast graphite comes to mind. Don

Fly rods should load with thirty feet of the rated fly line out. If they don't, they are marked wrong. Plain and simple, that is how that works out. I think the CCS gives us a guideline to go by, and I wish the folks at a couple of companies realized that rods are fishing tools, not casting tools.
