i shoot that bow and i go about things a little different. when i tune it to broadheads that's exactly what i'm doing. i find my perfect broadhead tune and my perfect field point tune are just a little different. i bare shaft tune to find nocking pt and then walk back tune to find my centershot. then i go back to 70 yards and see where i'm at. if i'm shooting down the middle, or within a couple inches either way i'm done. if i'm off a lot up and down i may play with my tiller. i usually find my field tips have a little different poi than my broadheads when i'm done. i could get them the same, but it wouldn't be perfect. i haven't tuned yet this year with bh's since i've gone to a floating yoke. i think this may help.
