The Snake Roll cast is another very useful cast to have in your armoury when fishing in a downstream wind, and your hand positions on the rod handle, in relation to the bank you are fishing from, are exactly the same as the Double Spey.
Reasons to have this cast in your armoury
This cast will allow you to cover the whole section of the pool in front of you, at any angle you wish (upstream, across or down) much quicker than you ever could using the Double Spey cast. It will also allow you to cover a visible fish very quickly, whether it is on a lie or moving upstream when it shows. We all know that running fish can be very difficult to tempt, but if you can present a fly to them the minute they show themselves, then you have increased the odds in your favour.
How the cast works
As with all casts, the Snake Roll cast can be used in a non wind situation, but like the Double Spey cast, if used in an upstream wind it can be very dangerous, although used in a downstream wind it is very safe and efficient for all the reasons described in the Double Spey section. As you become more familiar with this cast it can be made much more dynamic by altering the shape of the initial rotation and the length of the draw into your delivery position thus maximizing your available casting weight.
Here is the cast in brief:
The initial Rotation of the rod tip
You will notice that the initial rotation of your rod tip performs two important functions:
(a) It repositions your anchor point (e.g. fly, leader, end of fly line) so it is facing the direction you are going to cast to.
(b) It allows you to create a D loop behind your anchor point thus giving you the casting weight you require to make the cast work.
