Personally I'd go the route of the Partriot. The Liberty will have a significantly smoother draw but not near the speed...if you were coming from anything but the Mighty Mite my answer would be more neutral but the MM has the harshest draw of them all IMO due to the shorter ATA. I Shot the MM and went to a Patriot dually and everyone said how the draw was a bit rough but it's a creampuff comparitively speaking. Especially for the extra "umphh" downrange with the shorter drawlengths.

I'd stick with the Cosmic instea of a pendulum too, but that's just me.
