The arrow diameter was suggested by the boys at Black Widow the 125 gr. point also 2 when I first asked about the combination I should use that was over a year ago.
I started going with heaiver points when I found that the arrows consistantly flew to the left.
It finally got to the point where I just found an aiming spot that would deliver the arrow left of my POA and allow me to score bulls consistantly
But aiming 4 or 5 " high and right just didn't sit well with me; the arrow should hit close to POA if not the POA itself. I believe that I have found the right combination with the set up I have now. 2216 aluminums cut 30" with 145 gr points in front. I have shot this set up @ 20 yds for two days now and am satisfied with the results thus far as the arrows are hitting POA or very close to my POA.
