I know this subject has been beat to death and I've done a search and read lots about it but myquestion is my FOC is at 8.2% with the arrows I'm shooting now. Question #1 I only use my bow for hunting so do I need to up that % and will I be able to tell the differance between what I have now and 10% FOC or even 11%. Question #2 what is the best way to get my % up if needed. My arrows (gold tip XT Hunters) measure out at 28" I have 4" Dura vanes with a wrap and 90 grain field points. Any input would be great I might not have to mess with it but if it will help my accuraccy I'll change. Does anyone now what an insert and nock typically weigh and I suppose I should include the weight of the wrap does anyone now what they weigh. Maybe I should just leave it and practice, not sure what to do here.
