The Outback will be faster than the Liberty because the Outback's cam is designed to store more energy than the Freedom cam on the Liberty. The Freedom cam is designed to be velvet smooth with little emphisis on speed. A better comparison would be the MightyMight or the Patriot VFT with the Outback. Mathews dosen't make the SQ2 or MQ1 anymore, which would be a better match up with the Liberty or Justice. The Freedom cam is not a fast cam but is meant to appeal to those that want an easy drawing and shooting bow.
