New arrows / vanes

Made my new arrows ready yesterday. Put some XS vanes to four arrows and some K-vanes other four. Went to the practice field to test them. Weather was like +7 and still some snow in the field. Not the best weather to test some arrows, but that is what we get here north at this time of the year..
Started to shoot from 30m and shot old arrows and those two sets of new arrows. There was no difference between any arrows, they all hit the same area.
Need to test some more, when saying is there any difference between them. Hope that during weekend little better weather or at least little warmer. Needed to put couple long t-shirt that could shot. The field was still quite wet, so my boots soaked the and almost let the water in...
