I have 3 PAA brushes - Starcraft, Solar Flare, and the Green Ray. They all look great and are solidly made. For my preference the Solar Flare is a tad bit too soft but is still very good. The Starcraft is perfect and I like it by far the best. The Green Ray was on my list because I found the knot description very interesting. I bought it with the starter kit and believe the package is a great deal. I like it somewhere in between the other two brushes. The handle is a bit small for my hands but not uncomfortable. I was hoping there would be more backbone and it would be more like horse hair, but as the Starcraft description notes, it has more backbone than the Green Ray. I did not really feel strong similarities with horse hair other than color. As such, it was a bit of a disappointment only in that it did not meet my expectations - not in overall performance. It works fine, is smaller, and looks are better in person in my opinion. All their brushes have been good values. I only used it for the first time this past week and only have 7 shaves with it. I would recommend the Green Ray if you like the style, but ignore the knot description relating to horse hair. It is a nice addition to the collection, but not my my favorite brush to use. To me the Starcraft is the best PAA brush I have used.How do you like your Green Ray brush? I've two PAA brushes (Starcraft, Atomic Rocket), so the Ray is next on my list--pending some good reviews.
