I am shooting Fatboy 400's at 28" with 80 grain glue ins and 2 inch blazers, unibushing and super nock. According to the GT website, my foc is at about 6.79% and if I up it to 100 grain points it will put me over 9%. How much of a factor is this going to be in getting arrows to fly straight. I have a little movement on my arrows, but unsure of foc or if it is my bow or me torquing my bow. I know ideally your foc should be between 8-10 %.

thanks and good shooting
