I forgot to report back on my sock brewer. I've been using the same grind that I use for my Hario pour over brewer as well as the same spiral pouring technique . Overall I like the sock brewer a lot. It produces a more full bodied cup, kinda a cross between a press pot and pour over. I am definitely getting more oils in the cup. As with all cloth filters, cleanup sucks.
I'll try to get some pics of the pot in action. The coffee dripping off the bottom of the sock has a very zen-like quality.
