Tip
The level front end section of line — usually just six
inches long — allows you to change leaders without shortening the front
taper and thus altering the way the line casts.
|
 |
Front Taper
Tip diameter and front taper length determine how a fly
is delivered.
Longer front tapers dissipate
energy for more delicate presentations
Shorter front tapers transfer
more energy from the belly to the tip for powerful turnover
|
 |
Belly
The section with the greatest diameter, the belly also
carries the majority of the casting energy.
Longer bellies increase
casting distance and accuracy
Shorter bellies shoot better
and cast faster, but sacrifice accuracy
|
 |
Rear Taper
Rear taper length determines how smoothly you can cast.
Longer rear tapers transmit
energy smoothly to the belly for increased distance and control
Shorter rear tapers put the
running line in the guides more quickly for faster casts
|

|
|
Head
The head — formed by the front taper, belly, and rear
taper — dictates the effective casting and control range of a line.
Short heads cast quickly, but with little distance. Long heads offer
more long-range control, but require more false casting to clear the
head from the rod.
|
 |
Running Line
This section helps make distance casting easier. Running
lines are very lightweight, which permits the energy stored in the
line's head to pull the running line through the guides during casting.
The smaller diameter of the running line also creates less friction in
the guides, which promotes longer casts.

Basic Tapers
The pioneering work of 3M Scientific Anglers™ is
responsible for the great breadth of tapers available in fly fishing
today. We have made a science out of engineering the ideal shapes for
specific fishing applications:
|
Weight Forward (WF)
WF lines are designed to offer excellent fishability from
short to long ranges. The smaller diameter running line reduces
resistance for increased distance.

Double Taper (DT)
With identical tapers on both ends and extra long
bellies, DT lines are ideal for short to medium casts. They also offer
excellent long-range line control.

Level Line (L)
Untapered lines are the same diameter from end to end,
and, though highly affordable, they are more difficult to accurately
cast and control. Our lines offer the unique advantages of Scientific
Anglers™ core and coating technology.

Shooting Tapers (ST)
Also called shooting heads, ST lines offer maximum
distance when control and accuracy are less critical. Shooting tapers
attach to small diameter level shooting lines creating less resistance
through the rod guides, which results in the longest possible casts.
