You need tomeasure your balance point and do the math. The website is based on 'standard' vane weights. Blazers are considerably thicker and heavier than a regular 2" vane. Your FOC will not actually be as high as the program says.

Even if itIS over 13%, it won't cause any problems whatsoever. On the contrary, the high FOC will make the arrow more stable and eaiser to tune, assuming it spines out right. Many guys like to talk about arrows taking a 'nose dive' with FOC that high, but whenever you hear that you need to spray your BS repellent.

Trajectory won't be quite as flat as it would be with a lower FOC, but it's just like comparing trajectory ofarrows where one weighs 40 grains or somore than another. The arrow is NOT going to fly nose down. It is NOT going to nose dive past 20 yards. It is NOT going to be plowing dirt 20 yards before the same arrow with8% FOC will.

FOC that high wouldn't be my first choice for shooting spots at 90 meters, but for a hunting or 3D arrow, no sweat.
