I have a 2011 carbon Element with #3 cams. Set at 29 I have 28 mods also. RH 50 -60 great condition. I am looking for a Invasion Black Ops 50 -60 for trade in on bow for bow. I will give you selling amount for your Invasion toward trade. I am easy going and easy to work with. Only serious trades please. If you want the bow price it is $850. This is bare bow but will sell with extras if someone wants them.
