There are 3 program choices. SF is strictly for arrow sizing. SFA is for more detailed work. With that you can put in your bow info and check stuff out.

There's also Carbon Expressshafts that are 100, 200,300,&400. The CX series and the 3D Select size that way. 100 being the lightest. You will probably be in the 200 size with that set-up.300 may be too stiff. Terminator series uses 4560 & 6075.

If I was at home I'd be able to run the numbers for you but I'd agree with mobowhtr on the sizes that he recommended for Easton and for the otehr CX series.
