Does anyone have any experience with how accurate the Carbon Express spine charts are? I am looking to buy some terminator selects and am not sure which size to get. The chart says I need the 45-60, but I have heard that spine charts are usually underspined and you should pick the next size up. I'm thinking that could change from manufacturer to manufacturer.
My setup is a Hoyt Ultratec at 60#, 27" draw. I'm getting about 240 fps with a 440 grain arrow. Thanks.
