[quote=MN3][quote]too stiff [/quote] ???
you want stiff in a spin pole
this is for a windsurf sail but generally applicable to a spin pole
"If the mast stiffness is higher than what is specified by manufacturer we have:
A more stable sail, since it will deflect less
More power since we have a tighter leech
A fuller profile
This is a better option for heavier riders as they will subject their sails (and masts) to more power and the correct mast might deflect too much for them."
"If the mast stiffness is lower than what is specified by manufacturer we have:
A less stable sail since it will deflect with each gust, changing the power in the leech
Less power as the leech releases much of the power
A flatter profile
The sail will feel softer as the gusts are absorbed by the mast (like the suspension on a car)
This is better for lighter riders who want more control and speed when sailing on choppy water"
