Flight is more of a function of bow tune and shooter form, not the broadhead. That being said, assuming all things perfect and equal, the best flying fixed head will always be the smallest one with the least amount of surface area.
Take your pick of quality compact heads out there today, and spend your time worrying more about your practice and fitness rather than the name on the package of broadheads. JMHO.
Agree with this. If your bow is well tuned it doesn't really matter.
