I am in the market for some new arrows and am leaning towards the Easton FMJ 6mm arrows but would like to hear from some people who have used them. Are they a good arrow for both 3D and hunting? Since they are aluminum covering carbon, will I have to completely change my bow sight pins or should they stay relatively in the same spots? Also how do these compare to the regular FMJ's that I believe are a smaller diameter? From talking to a local pro shop the guy said they are good but pricey but really didn't have any real world experiece with them. Are there any other arrows that are aluminum covered carbon arrows made by other manufacturers? Thanks in advance
