RE: Mathews LX - Grip Vibration
I am not experiencing any with mine (extremely dead feel.....even with 350 grn arrows). Check your grip to see if it is loose. My MQ-1 began doing that a few years ago and I finally noticed that the grip had become loose. I popped it off and reapplied it with some 2 sided carpet tape and it was like getting a new bow.
Good Luck !!
