So, are we all sighted?
Be sure to shoot your practice broadheads into a broadhead target. This year, the POI from one of my rigs with broadheads was 3.5" high left of my field point POI, at only 18 yards - big difference.
This is arguably the single biggest advantage of fixed over mechs - the ease with which you can shoot them into broadhead targets to actually check zero, and then pull them out easily with no damage over and over. Yeah, yeah, I know - the whole point of mechs is that the POI will be the same as your field tips, so you don't have to check them, right? I call hogwash; would never take that chance. They might be "close enough" at 20, but no way you can trust it after that without actually somehow shooting a practice mech head into an actual target.
I ended up not buying a new manual bow this year - just the Hickory Creek Inline 125 vertical Xbow.
Gotta say, I've tried FOBs, I've tried vanes, I've tried carbon arrows, and I've tried other heads, and now I believe the best combo for hunting, generally, is:
--Easton FMJ shafts
--real feather fletching (usually the 2" Rayzrs), and
--fixed 3-blade monolithic heads (VPA Terminator, Red Feather Phoenix, Wensel Woodsman, G5 Montec, etc.) - super tough, super easy to re-sharpen, easy to pull of broadhead targets, penetrate through bone.
