Same shape as Zwickey except it won't rust and has vents to resist wind planing.

For stainless traditional heads they've really done a nice job.
But I'm curious! Why is it people believe vents will resist wind planning? I've always found that facinating. Isn't a car with it's windows rolled up more aerodynamic than a car with it's windows rolled down

Also, do people honestly believe "stainless" means "rustless"? I need to get the camera fixed on my microscope

Posting some pics might really open peoples eyes. And get people shooting some sharper broadheads too!
