Justin,carbon arrows act differently than wood or aluminum.As a rule of thumb you need to stay at 10 gfp but you can go up to 12 if you are hunting heavy skinned critters or limit your shooting distance.Usually people like a stiffer arrow and then load it with weights upfront to have a high FOC.I think you can use a CE,very tough arrow,250 cut around 29-39" with 100 grains insert and your 160grs point then you can add insert weight or cut 1/4" of shaft as needed.Remember carbon are really sensible to the lenght much more than Alu. make always adjustment of 1/4" at time.You can use a 150 if you like a ligther arrow.
