Wow guys.... My old bow is real QUIET!!! There is no "Twang-g-g-g-g-g-g-g" sound and no vibration in my hand after the shot. This is incredible!

Why didn't I do this sooner?!?!?
The guys at the bow shop told me that as of now, and after the review/checkup on my bow, there is no more that can be done to it. It's performance is maxed out now. It is still set and will stay set for a long time.
The bow that I flipped over was a Hoyt Ultramag(?) split limb, 70# draw, lefty, beautiful model bow! It was amazing and so smooth to draw. I couldn't believe it was 70#'s. It was a part of a package deal and was (I think) $500 something bucks!
