Is it really important to tune your broadheads to hit like your field points, or am I ok just tuning my broadheads to hit where I want for now?

what i do is practice with field points and get those sighted in. until about a week until opener then i start using my broadheads for practice, and get those sighted in,and before i go hunting i sharpen the blades

That's what I've been doing. I'll sight in with the field points and get them hitting good, and then I'll shoot one of my Muzzys with the practice blades and then get that hitting good which in turn moves the spot where the field points hit.

I try to get my field points and broadhead hitting together, but if I can't I don't lose too much sleep over it. I spend a lot of time bare shaft tuning to get the arrow flight I'm looking for. If I get the bare shafts flying straight and I'm punching bullet holes through paper, and arrow flight looks good with the broadheads on, I don't worry too much about where my broadheads hit in relation to my fieldpoints. I've had them close, but never perfect. I wouldn't recommend that you wait until a week before the opener to practice with your broadheads though. Give yourself at least a month IMO, depending on how often you shoot. Better safe then sorry.

By the way, this is my first year with the Slick Trick Broadheads. I bought them specifically for that reason. Theoretically, once I get my bow properly tuned and field points dialed in, I won't have to readjust my sights for the broadheads. Hope they work as well as everyone says!
