Apologies for my intemperate response. I imagine we are all looking to get the most enjoyment from our systems and any disagreements about how we achieve it are secondary. Let many flowers bloom. For me those little semi-spheres of rubber like material tick two essential boxes, 1)they are cheap and, 2) they work in that they help to make my system more musical to my ears.
Unfortunately I own no shares in the company.
I'm glad that tweaking still appears to work - I'm with Vonnegut - life's for pooping about.
Best wishes
