I show those arrows being stiff for that set up with a 85 grn point. Do you know how fast it will shoot them and what they weigh? I also need to know what type of nock you use. I figured it with the standard lock nocks.

I get a total arrow weight of 375 grns with the lock nocks and 85 grn tips. Also a FOC of 7% which is pretty low for a hunting arrow.

I would suggest a 125 grn tip weight. That would bumb you up to almost 11 percent FOC, make your spine better and give you around 411 grns for total arrow weight.

I will note that I could not find your bow in my data base so I used a bow with simular specs, actually a bit better and I guessed on string weight. So my calculations are probably not dead on, but they should be close enough and would err to the stiff side which is better than being weak.

This was with the OnTarget2 software for archers program.
