Default RE: Rotating/helical broadheads

I am drawn to the idea of the Crimson Talon air foil/helical broadhead. Granted it is marketing for sure but if some of these claims are true:
A top research scientist working on the International Space Station Program has developed a new way to achieve flawless broadhead flight.
By applying a patented variable degree axial flow airfoils to the trailing edge of broadhead blades - arrows are now spin-stabilized from the front. Traditionally archers have attempted to guide their hunting shafts from the rear with vanes or feathers - that's the same as trying to steer your car from inside the trunk! This radical departure from traditional broadhead design results in dramatically reduced aerodynamic drag increasing arrow speeds and flattening trajectories.
Spin-Tite Airfoil Technology™ improves ballistics - the faster the bow - the more spin-stabilization imparted on the arrow shaft! No more being penalized for shooting an ultra-fast bow. And because arrows are now spin-stabilized by the broadhead, wind-planing is a thing of the past.
The patent-pending Spiral Wound Channel™ inflicts the most lethal wound channel in the hunting industry. All our broadheads continue rotating as they pass-through producing the patent-pending Spiral-Wound Channel™ - a wound channel that cannot close or clot under any circumstance. The result is unmistakable blood trails and the most humane harvests possible.
then it would seem like you could use the spinning energy of the arrow to impart more killing damage to the animal. I especially like the way they compare it to a drywall screw. If you are at all familiar with them you will know that they pull themselves into and through the working material.

It sounds like rocket expandables are using the same concept.
