Thanks, Jeff thats exactly what i was looking for. I have been shooting CX 300 for 3-D and have been using CX 400 for hunting with Fixed 100gn BH. I ve shoot both with BH but the 400 seem to group better, so i guees ill try the 300 Axis. I read you were starting to get spine degradation with your axis arrows. Any guess on approxamatley how many shots you had on these arrows. Thanks, Dennis
