Re: What is a shooting head?
A shooting head is a 30' to 40' front part of a fly line that attaches to a running line. A shooting head gives the angler the advantage of not having to carry extra reels and spools, which also saves him or her money. Also, some feel shooting heads help increase casting distance.
On the downside, they can be awkward to cast. You have to have the whole head outside the tip quide if you want to double haul.
If you're using a 30' head, you probably want to use a line two weights up from your rod.
The recent thread on shooting (running) line might be helpful to you.
You can buy shooting heads or build your own.
