I don't care if you're the best archer in the world. Low FOC hunting arrows will be a disadvantage in wind, when hitting twigs or when contacting bone.

Aiming for some mid-range figure should not be considered ideal. If you're hunting real large game, or not likely to take a shot over 30 yards, then there is no real disadvantage to using very high FOC arrows. Extreme FOC arrows give substantial advantages in stability under less than ideal conditions and penetration on bone hits. It also makes tuning broadhead flight a lot easier. There is less tendancy for the front end to plane.

The average hunter does not super-tune their setups. They would be far better off using FOCs in the 17-20% range, rather than something midrange, like 10-12%. The advantages really show up with those that are less experienced. They simply need proper guidence in selecting arrows and tips. Any halfway decent shop should be able to do this. Trouble is, many shops slap 100 gr heads on every arrow, with no regard to spine and FOC. In my opinion, this is anything but professional service.

By the way, it's Dr Ashby's reports that you want to read.
