RE: Arrow Flight different with broadheads vs. field points
C903,
In a nutshell - I think what STICKEMUP was pointing out is as follows.
With a clean release one can fine-tune a wet noodle (way underspined shaft) to shoot perfectly out of a bow with field points. This is particularly the case when shooting a drop-away rest. This is not the case however when one shoots broadheads.
I happen to concur with this myself.
STICKEMUP, if I have misinterpreted your point, feel free to correct me.
C903 I hope that this has been of assistance in clearing things up.
