Here is a list of newby Skagit casting basics to get you started on your Spey Casting journey
1) (Besides backing and running line) you only need your Skagit head, a sink tip, and 3 feet of straight mono leader. Oh, and a fly.
2) Once you have attached the above set up you do NOT need to add any of the following. A polyleader, a versileader, a tapered leader, a cheater.
3) You have a skinny line, which is called either a running line or a shooting line that is attached to your Skagit head which is a fat line. Keep Skagit head close to the end of your rod tip to start with or even slide it inside the guides a few feet.
If this is all completely foreign to you start with half or even less of the Skagit line outside the tip-top guide. 10 feet of Skagit head + 10′ of sink tip + 3 feet of mono attached to a moderate sized fly (think Hobo Spey) will give you 23 feet of line outside your rod tip.
4) Safety Glasses are seriously a great idea or at least wear skookum sunglasses.
5) If you feel the wind on the right side of your face cast on the left side of your body. If you feel the wind on the left side of your face, cast from your right side.
6) With your short setup start with a roll cast.
7) There are two parts to every Change of direction Spey cast: The setup and the dynamic roll cast.
8) The double Spey cast is a great starter cast, provided you don’t try it in a situation where the wind will blow your D loop onto your body. See #5)
9) A Circle C or Snap T is fine to start with if the wind is wrong for a double Spey. With only 23 feet of line out it should be very easy to plop the fly down in a position where you can then roll cast it.
10) Feel the wind, Think set up….Then, roll cast. Gradually build your distance from there.
11) Watch the Above video, Play with the D loop drill. Gradually get used to the two-handed rod, The D loop, the setup and the roll cast.
12) Give yourself time to understand the basics of Spey casting with the shortened line and one day soon with some thoughtful practice you will be “bombing casts”.
