I shoot the Easton ACC Superslims. I currently am shooting 100 grains with my set up but I am changing to 125. My question is this I don't know what size field point in diameter to order from Cabelas. I don't want the field point to be greater in diameter than my shaft. The 3 options they give me in size for the 125 Grain Field point is 11/32, 9/32, or 5/16. Any assistance would be greatly appreciated.
