That's the only one of the 12 factors I haven't incorporated into my setups. I also haven't bought any premium brand arrow shafts. I'm mostly looking for lower numbers on the GPI (grains per inch) while still maintaining correct spine. I'm running about 400 grains up front and that puts me in the 25%+ FOC. Running feather vanes also makes a huge difference. Just a few extra grains way out on the end of that fulcrum arm (Shaft) will really rob you of some FOC.
