A fly line that I have had specifically design for the cane rods that I make, and the type of fishing that I do; small stream and river work with occasional trips to the remoter lakes.
Working closely with the best line manufacturer in the country and applying the same principles that are used in rod design
I now have a line that I happily recommend for use on my cane rods and one that will work equally well with carbon rods.
The basic profile of the line is weight forward.
However many modern lines have a simple straight front taper from the body of the line out to the tip. This is OK, however it is not ideal.
A cane rod that has a straight taper will be OK.
However it will lack delicacy in the tip and it will also lack power in the butt.
So it is with a fly line.
A simple straight front taper will lack power to turnover larger flies or punch into a wind.
It will also lack a delicate transfer of casting energy out into the tippet.
By using a compound front taper you get the best of both worlds,
the steeper initial transition from body into front taper ensures that all the power of the cast is driven forward through the front taper,
then as the power nears the tippet the transition becomes more subtle ensuring that the tippet is not over powered.

The line are available in 3wt 4wt 5wt and 6wt.
To keep costs down the lines are sold without packaging.
The lines are floating and Olive in colour.
I have also had a few lines done in a bright orange.
These were specifically done for rod makers so they can have a line that loads a rod quickly and will hold a good loop profile at distance. This makes it easier to evaluate the action and casting dynamics of a rod.
Olive is an excellent colour for a flyfishing line, but it is difficult to see precisely what is going on with the line.
If you are a rod builder get in touch.
I've also been reliably informed that the orange is excellent for beginners/practicing/teaching as it's possible to easily see what's going on
and to demonstrate what should be going on with the cast.
The Olive and Orange lines have the same taper profile and have the same casting characteristics.

These lines are made in England.
