The amount of line exposed to the rear of the caster is also of paramount importance.

During the concluding moments of a Single and Double Spey or Snake Roll, a 'D' loop is formed alongside and to the rear of the caster. Optimal 'rod loading' is achieved when the 'D' loop is at maximum stretch and the fly line 'Head' and rear taper are almost completely outside of the tip ring. If executed using a perfectly balanced line, this 'intentional hinging' of the rear taper not only improves the potential for narrowing the loop in the forward cast but it also increases both line speed and distance….we call this the 'Optimum Rod-Load Point'.

On large open rivers there is normally plenty of room for Spey-Casting and the size of the 'D' loop is not a limiting factor. Spey-Cast your way down a tree-lined river and suddenly there is another Dimension to think about.

This situation is made more difficult when the caster uses a line with too short or too long a head and finding the optimum rod-load point is left pretty much to guesswork. The Snowbee development team has tackled this situation head-on and produced a range of lines that are perfectly balanced for Spey-Casting in just about any river environment..

1-D Spey Lines (51ft Head) - Suitable for Spey casting in Small rivers where bank-side vegetation and / or steep sided riverbanks severely limit the back-cast area.

2-D Spey Lines (62ft Head) - Suitable for Spey casting in Medium sized rivers where bank-side vegetation and / or steep sided riverbanks have only minimal impact on the back-cast area.

3-D Spey Lines (73ft Head) - Suitable for Spey casting in Large rivers where bank-side vegetation and / or steep sided riverbanks do not encroach on the back-cast area.
