RE: Broadheads that fly like field points?
Expanding on what Len said, you can get any broadhead flying to the right spot if you not only do what he says, but do particular things when designing your arrow.
That would be: Put lots of weight up front, ton's of drag in the rear, a spine that is correct for your setup (this is a whole lot more complicated than just choosing an arrow from a spine chart). Then, build it correctly and tune your setup the right way.
When broadheads shoot to different locations, that is because they are being affected differently by outside forces. To eliminate these differences, you have to build your arrow for stability, so these forces are reduced and/or have no noticeable effect. In addition, some broadheads have a design that exaggerates any problems in the setup. That doesn't mean you can't shoot these effectively. It just means you have to know what you're doing to get good results. It's worth knowing how to do this
Shooting a broadhead because it flys good out of your setup when others don't is not the best solution. It means your setup is not tuned optimally. It's what I would consider a bandaid approach which is never the best way to go.
