I have not spent nearly as much time with the GP as I have with the wing paddle, but from what I've done my feeling is that the outward sliding wing stroke is best done with ... a "real wing" paddle.
The reason is that this kind of style requires to keep the hands and arms tall and the paddle quite vertical to the water to be effective. But if I do that, I might as well have paddle that offers more purchase on the water and has a greater lever (wider spacing of the hands on the shaft) without the need for sliding a hand out at each stroke. This kind of stroke IMO is reserved for active and fast paddling and for that purpose I feel a wing is better. For slow paddling, this kind of style does not seem to make much sense to me...
For longer distances at less than top speed with the GP I seem to prefer the stroke that dives towards the hull, then slices out at the exit. Both phases generate forward lift component, so in a way that is still a "wing" stroke and is efficient. But as Greg Stammer's article mentions, this style has 2 distinct phases, unlike the slide-out syle where there is a single outward swing.
Lastly, some do more of a "S" path through the water - slice towards the hull, then slice outward in a "wing" stroke. That requires good rotation and seems to be similar in effort to the simple outward slicing "wing" stroke...
RPG - try a wing if you have not: you might like it, better if you plan to use the GP in that style -;) |
