I shot the new Liberty today and all I can say is that what everyone is saying about this bow is very true!!!! Very smooth and very quiet with nothing going on but arrow delivery. No shock or vibration and I did chrono it against the speed tag on the bow. The tag said 60/29 and with a 300 grain arrow did 289 fps. My findings were that with a 302.1 grain arrow it went 291 fps and with a 356 grain arrow it did 271 fps for 58.07 foot pounds of energy. If you can't blow through a tender little whitetail with that, you must be trying to shoot one ene to end!!!
