Furled vs. Single Strand
I wrote the bulk of this in another thread which was discussing leader choices for reeled rods. The basic concepts are the same for tenkara lines, so I thought this might be helpful if you are considering what type of tenkara line you might want to fish.
I think one thing that is useful to keep in mind when deciding what kind of line to use is the understanding of how they perform.
The purpose of all tenkara lines is to transfer the energy generated by the rod ultimately to the tippet and the fly. Different line designs use different methods to accomplish this transfer.
Typically, a single strand line relies on the inherent stiffness of the material. So in effect, it works like a bow and arrow.
A furled line on the other hand does not rely so much on stiffness, rather it relies on it's own inherent mass.
So to greatly simplify, a single strand line can be relatively thin (diameter), but needs to have some level of stiffness. A furled line doesn't require stiffness, but it needs more mass which usually equates to a larger diameter.
So where alot of this comes into play is how the line reacts when it does (or does not) come in contact with the water. A single strand line is thin, so it provides less surface area to cross currents, but when a segment of the line is moved by a cross current, the stiffness causes that movement to propagate thru much of the rest of line.
On the other hand, since a furled line can be fairly limp, a segment can be moved by a current and is limp enough to cause a bend in the line, rather than dragging the rest of the line along.
SO when it comes to line choice, alot depends on how and where you plan to fish.
Hope this helps.
