True, it can be a bit OTT. I don't use it fully jammed into the the strings so the rubber's touching the body but inserted lightly, right by the bridge, and sometimes at an angle to get the sound I want. Works for me.
I use the 20mm on the 4 string and 19 on the 5.
I personally find the NordyMute, while nicely made and convenient to use, is too dense and over-mutes.
