Sorry about the delayed response, life got in the way.
I’ve been using some of the TFO fly lines for about 2 years. I’ve spent more time with a 5 wt line than any other size, and I’ve like it. They are designed to be general purpose lines and that is how I’ve been using it. This year, I’ve used the same line for double nymph rigs at Beaver’s Bend, dry fly fishing in Yellowstone, and for warmwater fishing in rivers and lakes around the DFW area. I have been happy with the line in each of those situations.
The line is made by Cortland for TFO and their logo is included on the packaging.
The lines use a general purpose taper design, but the actual taper varies based on the line weight. The lighter wt. lines use more of a presentation style taper, the middle wt’s use more of a traditional taper design, and the heavier sizes shift more weight toward the tip and use more of a rocket taper or bass taper design. The change in taper design matches how many of us fish. If I need a stealthy presentation, then I’m more likely to use a lighter wt line, and when I’m using heavier lines, then I’m probably more worried about casting larger flies over longer distances.
The plastic used in the lines is also designed for general purpose. There are other fly lines that are designed for very cold conditions and there are lines that are designed for very hot conditions. The TFO lines are not designed for the temperature extremes, instead they use a plastic that functions well in the middle temperature ranges that most of us actually fish most often. The coldest water where I’ve used these lines were some of the higher mountain lakes in Rocky Mtn National park. The lines performed fine without any memory issues, however, I have not used these lines in conditions where it is cold enough to form ice on the rod guides. If it is that cold, then you may be happier with a true “cold water” line that is designed for those conditions. On the other extreme, I’ve had no issues using a TFO line in the heat of a Texas summer, but if I was headed to an island for a bonefishing trip, then I’d get a different line that was designed for use in “tropical” conditions.
Some general fly line comments. Rio, SA, Cortland, and most other major brands have three levels of fly lines available. There is a budget series that is often found at some of the big box style retailers. These lines have their place, but I have not been impressed with their performance. At the other end of the spectrum are the “premium” fly lines. These lines have the newest plastics, additives, coatings, surface finishes, etc. These are the “high performance” lines and if you have special fishing conditions or a “trip of a lifetime” planned, then these are the fly lines that you want to take with you, but you may not need the “latest and greatest” designs for your daily fishing trips.
The middle of the pack fly lines is where the TFO fly lines are competing. These lines tend use more general purpose tapers, designs, and may be a generation behind in their plastic composition, but these mid-range lines have worked very well for the way I fish.
I spent most of my actual fishing time with a 5 wt TFO fly line on either a 5 wt TFO Mangrove or a 5 wt TFO Pro rod. I’ve used it for both dry fly fishing and for casting nymph rigs. It has performed well with both short distance accuracy casting and with longer distance casts. The comfortable casting distance does seem to top out at about 75 feet, but I seldom fish a 5 wt anywhere near that distance.
Bottomline, I’ve been impressed with the TFO line’s performance. They are general purpose lines and they’ve worked well for me.
