To date, now counting into the dozens, I have NEVER had a Flyer.
They simply Shoot Very Well.
I do test each one with field points, and NEVER aim at the same bullseye (for obvious reasons!).
When it comes time to test broadheads, I pick up one extra package of three.
These are then run through all the arrows I will be using that fall. Using Spitfires, I have never had to adjust the scope much. They fly extremely close to the field points. These are shot at ranges from 20 to 90 yards. Not that I will be shooting at critters that far off, but it sure is a Confidence Builder to see them group very well at those extended ranges.

Cheers,
