I recently bought a dozen GT 7595's. I have them at 27" and shooting them at 71#. I ditched my wraps and put in 22 grain nocturnal nocks. My broadheads are 100 grain. This works out to be only 8.77 FOC. Does this sound like a problem? I know that at least 10% FOC is desired...I know the true test will be when I actually shoot them. These arrows are also on the stiff side I know. I guess I could always go with 125 grain heads and solve both FOC and the spine but I will lose speed. Thanks for any imput.
