If you want to see the differences in various FOCs for your setup, I'd suggest tuning at 40 and 60 yards, in higher wind, while shooting broadheads. Whatever is wrong, will show up. Experimenting with FOC under these conditions will clearly show the differences.
As far as testing FOC in the wind, Rick from Carbon Tech told me the same thing. Great info and thanks for the reminder. The problem is, it’s hard to find wind or high winds while living in California.
