I've been testing mine (22g) over the last couple days. Definitely see a marked improvement over my traditional double. I had to pick up a naked PF, because mine simply wasn't deep enough. On first look, the holes are very evenly spaced, all go through and the pattern goes all the way to the edges of the basket. First attempt: Weighed 22g and used normal dosing/tamping technique. Not bad for a first attempt at using a naked. Only a tiny pinhole along one edge. Pour was spot on. Second attempt: Same weight and technique, with just a minor adjustment for the previous channelling. Extraction was perfect, no complaints. Impression in the cup: Compared to standard baskets, there is definitely a difference. Getting much more well-rounded flavours, and better mouthfeel. This can be attributed in part to simply having more coffee in the bigger basket. However, there is just so much more going on in the cup. Definitely better IMO.
