Yet another quick image post from me, and this one isn't colour related.
Now and then I still spot posts where people mention that the Guardian pommel is "quieter" then some others. I don't find mine is that quiet and so I went to have a good look at the pictures provided by US (which may be of an older version of this pommel). Here's a pic of mine.

If you go and look at the pictures in the Main site page for the guardian you'll see that it's more like drilled holes, which would be more restrictive.
One of my hobbies is car audio and I can say that the style of Grill over a speaker can make a fair bit of difference to the sound.
