cams

[iawalleyeguy]

i have a bowtech general 70# and am looking to start building my own arrows seems like all the spine charts ask if you have medium cam or hard / single cams not really sure where bowtechs binary cam system falls it seems to make a big difference in spine selection can somebody give me some help

[J.C.]

binaries are considered hard cams. if it is borderline between 2 spines on the chart, go with the stiffer one.
