Q Can you tell me the impact of vane stiffness on arrow flight? I don't know if you have any review about these problems showing the advantages and inconveniences of each vane about arrow speed, shock resistance, rotation speed… There are several models of vanes with hard / medium / soft / ultra soft stiffness from elivane / spinwing / xs wing / spider vane / K&K / gaspro and I don't know what to choose. I currently shoot with 2inch medium Gaspro but at each practice I have to refletch one or two arrows at least. The vanes are brittle when shocking each other and it cuts the ligature.
A spin vane must maintain integrity of shape and structure whilst the arrow is in flight. Upon release the force of the air striking the profile of the vane will start a rifling motion. If the vane is too floppy it will deform under the air pressure and will no longer be able to provide the consistent functions
