Tough question, kinda depends on what I'm after...
I've used all of them with success except for the single bevel.
Whatever the head, I like big broadheads.
Zwickey Delta 4-blade
Magnus 1 2-blade
Snuffer 160 / Big Jim "Big-3" / VPA 1 1/4"
Will use smaller 3-blades if penetration is in question... large boars, or if I were heading to Africa. VPA's, Woodsmans, Razorcap and the like...
If I'm forced to use a lighter head (125), the original Snuffer 125 screw-in, Snuffer SS, Razorcap, or Magnus Stinger 4-blade. Haven't used a narrow 2-blade (anything less then 1 1/2").
