I'll re-post an email I sent Jeremy so others that may have similar questions can hopefully find an answer.
The tapered lines Eddie Yamakawa taught me how to make have a very specific sweet spot with Tenkara USA rods.
The TUSA rods are softer in the tip sections than many of the rods that are made by Shimano, Diawa, Nissin, and Sakura. The TUSA rod line up casts the 16-24 ft lines very well, once you start getting into the 28-40 ft lines you need 7:3 or 8:2 rods in the 14-15 ft length to get the most out of the line.
When you use 20 + ft lines with 13-14 ft rods, there will be line on the water perhaps 4-6 feet. It is impossible to keep all the line off of the water, not because it's heavy, it is just simply the fact that the rod is not long enough to hold that much line up off the water. You really have to have a good feel for your rod and line combination to get good hooksets because you are having to pull slack line up when there is a strike. I use these really long lines for wide streams and very deep pools. The fluorocarbon lines sink pretty quick. I don't think they are a very good dry fly fishing line, Chris's tapered lines are a lot better for that.
Here is a link to a video we shot a couple of days ago. This is a 32 ft line being cast by a Diawa Sagiri rod. Keep in mind that this is a very light 13 ft rod designed to target fish in the 16" and under in size. By all logic, this rod should not be capable of managing such a long line. Just watch the video for yourself and you can be the judge. There was also about a 10-12 mph wind when we were filming this. http://www.youtube.com/watch?v=SBrY_lSF6EM&feature=plcp
Eddie's long lines work so well in wind because the base sections are heavy with a very small diameter compared to mono or kevlar lines of a similar construction. This mass propels the rest of the line with some real punch. Casting these lines requires a very light hand and little power of the forward cast. Keep a relaxed grip on the rod and let the rod do all the work. The more power that you put into the rod will put more power down the line on the forward cast and if it is too much, the tippet gets a pretty violent shock and has a tendency to bounce back toward you. If this is happening, just relax your grip a little and don't put quite so much power into the forward cast.
It takes a little practice to get the hang of it so don't get all aggro if your casting is a little funky the first few times you cast these lines. If you see that your line is rolling out too quick on the forward cast, just watch it unroll to the tippet and gently reach forward with your casting hand keeping the rod tip up and that will take some of the velocity out of the line. Watch the video closely and you can see me doing this.
Hope this answers some questions. Chris makes a really good line it is just different than the lines I make. I wouldn't say one is better than the other, they are just very different. Twisted or furled lines are a love it or hate it line. EriK and I love them, our partner Rob, not so much, he prefers level lines in the under 20 ft lengths. Like I said one is not better than the other, they are just different.
The best thing I can suggest is that you get one of my lines and one of Chris's lines and test them to find out which one works best for your casting method and fishing conditions. You will probably find that one works better for you than the other or you will develop a preference for one line over the other depending on the conditions or water you are fishing that day.
If you have any more questions about my lines, don't hesitate to ask.
