: Which means reducing to zero?

: No, it is a foil so you need to reduce it to a small foil section blade.

: If you apply it to cycling (more strokes), higher (within limits) spin rates
: are more efficient, not slow "slogging".

: No, loading and movement e.g. movement with heavy loading vs more movement
: with light loading - the second will lead to the same output with less
: stress on the body and joints leading to long "life".

: As above - no.

: A feathered Euro would have less wind resistance.

: Doesn't apply to the original GP builders. Splicing, dowels etc. were all
: available so they could have made their blades as wide as they wanted to.

: No, the Euro has evolved into the wing - which is just a GP with a greater
: thickness of foil.

: So??????

: Alex

A wing paddle is "not" a euro with a thicker foil. Might go look at a wing paddle and see for yourself. Can't even paddle with a wing like you would with either a euro or a GP or you'll go swimming.
