Shoot it and find out. You ain't going to see much difference in height until you shoot at least 30 yards. It only changes your speed about 5fps. Probably just gang adjust unless you shoot longer.

For example, just today I was shooting an indoor 3D with arrows 65grains heavier than my sights are set for. At 20 yards there was only about 1" difference in elevation. My speed went from 295fps to 270fps and all I had to do was change my ming. Instead of my pins hitting right on at 25,35, and 45 yards they were hitting at 20, 30 and 40 yards. I didn't change the sight at all. I just changed my thinking.
