You will see in my signature line what I am shooting currently. The reason I have CX Maxima 350's is because I recently changed limbs from 70# down to 60. It is obvious to me now that I am shooting a rather heavy arrow. I am accurate to 40 yards though and I am getting 250 fps with this. Other than a flatter tragectory and increased speed with a lighter arrow, what am I giving up or gaining with this combination? Are the benefits truly enough to justify the cost of getting new arrows?
