Check out the tuning manual. Very good info. First, even before spin testing, make sure the bow is tuned. Then, after spin testing, yes, shoot one and see how it flies. They may or may not hit with your field points, the group is what you are after.

The keys to good broadhead flight include not only tuning your bow, but tuning your arrows. Spine should be adequately stiff. Borderline spine is not so good with broadheads. Spine testing your arrows is very beneficial if you can do it. Making sure you have adequate F.O.C. will help. I like to keep it over 10%. Putting a helical fletch on your arrows will help a lot also.
Combine all this with a well tuned bow and you'll have great flying broadheads.
I have found that lots of archers try to use too littel fletch on their arrows , shooting broadheads . I like 3 5inch feathers , or 4 4inch feathers for fixed broadheads . Trying to tune a big cutting fixed head with , say 3 3inch vanes is fustrating , and futile .
Straightarrow has given good advise , I see lots of archers shooting 29" 400 spine arrows at 70 pounds , way underspined

I personally shoot broadhead arrows and field point arrows at the same spot. If the broadheads are off, I adjust the rest and nocking point until both types of arrows hit the same exact spot. Bare shaft tuning would accomplish the same thing.

I just set up my new trophy taker and I got it to shoot field points and broadheads. I shoot a broadhead and field point into the same dot on the target. I have three dots and shoot three times (six arrows). Then I usually tweek the rest L to R to make them hit the same. Be sure you only move the rest a "hair" at a time. Good luck.
After the bow is sighted in for field points I will proceed to shoot the exposed blade broadheads to see if there is a difference in the point of impact. If there is then I make the appropriate adjustments to my nockset height or arrow rest position. The Easton Tuning Guide linked above is what I typically follow. All have given some good advice though.

Now a Question,
You paper tune and move your arrow restposition or nockset height to shoot bullet holes,
Now your going to move it again to adjust for broadhead flight, well you just screwed up your paper tuning. Am I correct? They both can't be right. Just wondering about this. It's like you can't have your cake and eat it too.
