I have the recurve limbs on the Excalibur. Very simple, no cables, no wheels. It's a 200 lb pull, lightening fast. I also use Muzzy MX3 broadheads on Easton's full metal jacket bolts. So far, two shots two deer. Something that has been a great surprise: both deer had massive damage to their lungs from the crossbow vs when I shot a recurve or compound bow. I mean the lungs came out in a slurpy mess. Anyone else see this using crossbows? Normally, you see a tricut through the lungs but the damage to both deer was massive.
