If you want to use a drop away for IFAA, I would suggest an "original" LimbDriver with the target blade option installed. I noticed others suggested a "hunting" type drop away, I feel you would be much happier with a target style drop away for your competition.JMO
i have been shooting the original limbdriver for a long time now from spots to 3d to hunting I will not use any other rest. easy to set up and tune. I have not found a bow that it does not work on. I am a huge fan boy of the original limbdriver I own 5 bows and have that rest on all of them.
