I've been using a Merkur 38c Barber pole with Red Israeli Personnas. I also have the Merkur Vision, which I rarely use. The 38c is good, but I want closer. What about open comb? Or the Muhle R89? Has anyone reviwed Joris Plisson yet? Aslo, I've tried the Derbys, Crystals, Wilkinsons (German), Merkurs. The RED Israeli Perssonnas work, by far, the best.
