I've had this question alot, but never think of it while I'm in the forum. Finally I remember to ask it. Do any of you have tricks for dealing with or reducing the vibration from trimming? If I trim for any length of time over say 5 minutes, when I am done I still vibrate. I've also noticed that my grip feels weak after trimming. The longer I trim the worse it gets and the longer it takes to get back to normal. I run a John Deere trimmer, straight shaft dual string (can't remember the model). I've noticed this with all trimmer that I have used though. I was wondering if anybody has tried to do anything with the grips such as foam grips or rubber bushings or other tricks to absorb vibrations.
