I recently bought a used mathews z7, 27" draw, 60-70 lb limbs.I have not bought arrows yet for this setup and have debating heavily between easton full metal jackets and the victory VAP. My goal is an accurate arrow out to 60 but with enough kinetic energy to take care of an elk. Also should I stick with 400s or 340's if I go with FMJS as this setup is king of inbetween the two
