The Bohning Alpha Vane Arrow Fletching is a design that combines stealth, speed and torque. The vane is made in Bohning's AR1250 material which is the stiffest and quietest they produce. The vane profile has an advanced Torque Apex, which is the position on the vane providing peak rotational torque, combined with a gradual taper to the tail of the vane which creates the optimal balance of spin and stealth. At the rear of the vane, you will see a contoured tail which minimizes vane flutter. Less vane flutter reduces noise and helps retain speed. The low profile allows clearance on even the tightest set-ups. Bohning's AR1250 Material is a stiffer material that allows for fast, ultra-quiet flight over longer distances. Bohning's stiffer material also provides maximum speeds when fletched at a 1 degree offset, while staying silent. Bohning AR1250 is also the company's lightest material. All Bohning vanes are pre-primed and do not require vane cleaning or pen primers. Bohning recommend B...
