i too would take a broadhead tune. if i can get a full sized 3 fixed blade head to fly with my field points at all my distances, i found that my other tunes are right on. ive checked group tune and walk back tune and both were great after broadhead tuning. i find broadhead tuning to just be easier for me. and after the broadhead tune i HAVE watched long ranger groups shrink and shooting become more consistant.

paper tuning is just getting things close to being in tune. if you only shot 20yds all day every day, you might never notice if your bow isnt in perfect tune...but shoot at 30, 40, 50, 60+yds and you can and will see groups open up and/or arrows angled oddly or groups impacting left and right of where your vertical zero is...(ie you shot dead center at 20yds but at 30 you hit a little right and 40 you hit a little left...)

if i cant have my broadhead tune id go with a walk back or group tune...
