Anybody have ant thoughts re using 2 Herbie's tube dampers on 1 tube?

I'm already using Herbie's UltraSonic SS on the 6SN7s in my amp. I'm definitely happy and believe they make a positive difference. I've noticed that in some pictures of a number of tube amps that some folks are using more than one of the "rubber" style dampers on their tubes. Does anyone have any ideas?

Two balance out vibrations the same way holding anything in two places does. 
However test, listen and see.
But first, try the tubes again without dampers to be sure you weren't just fooling yourself the first time. I prefer no damping.

More than 1 will deaden and over damp the tube.Herbie are the best because they don't over damp like all the others.

Interesting question...I use one on each tube in my pre. I never thought about using more than one.

remember for any signal tube, what we are trying to do is to MANAGE microphony, not eliminate it
