Looking really sweet.
If you alread have arrows, you might consider adusting the arrow pass to match the arrows. E.G, make it closer to centre shot, just a few extra mm off the pass will make quite a difference.
I have two lots of arrows 70 grain points about 30 spine and 100 grain points about 40 spine. On the Osage I just made the 100gn felt best but shot a few inches left at 10yards, about 3mm off the arrow pass made 'em group about the same as the lighter softer arrows.
Dunno if that is of any use to you.
