There is defiantly a advantage to a high FOC arrow.
There is no reason that a high FOC arrow can not be tuned properly .Most who experiment and achieve UEFOC (over 30 %)
actually shoot arrows with a minimal amount of feathers and have tuned bare shafted with perfect flight.
If one is satisfied with the old standards which work ok( I know I used that standard for 20 + years) they will never know the beauty of a well tuned high FOC arrow
