Vibration creates noise and noise can cause animals to jump the string. Definitely not a gimmick. Whether quietness is important to you personally is another matter.Absolutely agree on the whole vibration, or how it’s put now, “hand shock” thing. That is just gimmick that only matters as six feet in the shop. I can’t say it’s ever mattered to me when choosing a bow. I love the shoulder punch of a good 30 cal rifle so the little buzz in my hand being an issue is comical.
Besides, once you have sight, bars, rest, and quiver on there, it is not the same bow.
