just read an article where they tested all the different products, from string to limb noise vibration items
from start to finish, the most they could drop noise was like 3 DB, and vibrations, well, again a small amount!
so to be honest, there is very small gains in all them items in my book
I will look for the mag/atricle and post later
it all can help, but there no magic item to make it quiet, and vibration free!
