Well I have little to offer because I have not shot either bow or one with a heavy vibration. I will ask that what is important to you is different than the others reporting back to you. For example, I just love to shoot and I am not sure if I want to hold a vibrater in my hands while I'm out at the range with the fellows. To me, I want speed and accuracy. What is important to you? When you have that answer, you will find your bow. Good luck and enjoy shopping. Kodiak, you sound like an engineer. What's to engineer in AK? Pretty ignorant on the the state but i know that I would love to head up there for a vacation.
