Overhang is the line between the tip of the
fly rod and the end of the rear taper of a weight forward flyline (including shooting
heads).
Too much overhang, during a false cast, is the quickest way to look
a dick that I know.
There are a few points to consider:
The more line outside the tip of the rod; the greater the bend in
the rod we can create, and
The more line outside the tip-ring the longer it takes for the
loop to straighten (this is a key point; not enough line and the loop straightens before the cast
has fully shot, too much and the loop fails to straighten).
The
longer the head, the more overhang you can maintain. This is why:
There are two ways to utilise overhang:
The backcast shoot:- discussed previously.
False casting with overhang:
It is quite simple to false cast with 2 or 3 yrds of overhang, however in order to
have a longer overhang it becomes important to cast a tight fast loop by hauling
as the 'stop' is made.
For very long casts (say 40 yrds with a WF5 - including
leader) ten yards plus of overhang is required.
