Snap T, C, V, the Circle Spey, e.t.c.

This series of casts replace a single Spey cast (normally) with a waterborne anchor cast in two moves. First a line placing move followed by a second sweep involving an initial peel or tear of the line lying on the water surface nearest the rod tip merging seamlessly into a powered D loop forming move opposite the target direction. There is some confusion between the classification of various casts and how they should be performed or named. I will not get into that but simply teach what I was shown and understand, always open to correction. There is a downstream side snap C cast.

The Snap T or C are excellent upstream wind casts used as a replacement for a single Spey. They are fairly easy to learn and very useful. The snap C in particular IMHO as the line placing on the first move can be directed better from it. The Snap C or T are so called because of the faster under the line movement of the rod tip to the finish of the first line placing move. Personally I do this at a more even tempo considering the snap can be done too rushed. I watched how casually Alan Maughan made this move and it influenced me to do likewise. On the initial line placing stage when the rod returns to the position it started from or further past that downriver, the end of the line is very cleverly flipped upriver.

On a Snap T tension is built up by steadily lifting the line upstream at a slope over the river and at an angle of approx 40 degrees or less and then when the rod tip has made progress far enough to be about level with the anglers position without any hesitation or delay whatsoever an angled slice downstream and just under the tensioned line is made. it is not a powerful drive but a crisp sweet move, a feel for it is developed. The point is there is no pause, its a one movement motion with a change of direction occurring in the middle of the move. I often curve the line in towards my own bank also at the end of that move with longer lines. The end of the line is cleverly flipped upriver with the energy of the downward drive of the rod tip. That faster downward return part under the line being referred to as the snap. It should not be done so hard that the fly line unrolls and kicks in the air, but that it unrolls with somewhat dissipating energy and drops gently onto the river surface straightening out as it does so.

Due to the curve in of the rod tip towards ones own bank if made, a curve of line is created on the water below the angler which uses up some of the spare fly line on a longer length of line, the anchor will then be in exactly the right place in relation to the angle as the D loop is formed on the second move. It will not be too far upstream if a longer belly Spey line is used. Using this curve in at the end of the downward snap, depends on the length of line out.

A Snap C is a much, much more popular version of the Snap T cast where the initial line placing move is less of an angled slice and a more open and rounded oval or teardrop shape. Also an upstream wind cast replacing a single Spey. The direction that the initial circular line placing motion is made in a snap C can be used to direct the line more out over the river if necessary by using an in swing to start the move.

A Snap V, rarely seen, is like a snap T in that there is a narrow gap between the rod tip return and the already lifted part of the fly line, but the V is returned over that lifted angle of line instead of under it.

A Circle Spey is considered a different cast from a Snap C for some people, In that the movement is longer and more open, higher, traveling well past the angler before returning and there is no snap.

There is then a second D loop forming stage after some line peel or tear. The D loop power application seamlessly merged into from the peel or tear and made with opposing leverage, upper body rotation, a slight pause as they are waterborne anchors, and then the final delivery. A large change of direction is able to be made easily from these casts.. Timing for making the second half of the cast is not too critical. Exactly when to make the D loop and final delivery of the cast can be largely unhurried and decided by the angler depending slightly on current rate. Peels a D loops are easy with these casts as the peel or tear goes against the current unlike a double Spey where it is coming with the current. As the tear goes against the current there is more tension and feel than on a double Spey tear or peel. It feels much easier moving upstream on a peel or tear.

There is a downstream side variation of a Snap C that is a useful enough replacement for a double Spey if there is plenty of room. This involves an opposite direction to a snake roll lift and loop the loop move on the downstream side, however the rod tip ends up pointed directly in front of the angler and low to the water. The line then drops on the water in a large crescent on the downstream side and with enough slack created to allow the formation of a D loop. The tear and D loop is then formed moving downstream and on the downstream side, after a slight pause the final delivery is made.
