I make sure my broad heads are tuned and they fly just like my field points. Also, a well tunned bow sould not have that much difference, that is if the arrow is tunned for your set up as well. I have not had problems with broad heads flying different than my field points since switching from thunder heads about 10 years ago. Every now and then, Id get a flyer with thunderheads. Ive never had a problem with slick tricks, Muzzy, orNAP fixed heads, or any mechanical.
