Hello, I received an order for a custom 11 line Megillah, it is for an Adom Chashuv and the person who is buying it for him wants "all" the Hiddurim. He also wants the ksav to be very large since it is for an older person so about 1.6mm or 1.8mm per line. When I called my Klaf contact to order the special sizing he mentioned that there is a new tikkun from R' Chinagel on the 11 line Megillah that is more Mehudar. Basically, the columns are much narrower and therefore they are taller than wider so it is more Mehudar. I never heard of this extra Hiddur so I called R' Chinagel and he told me that the Hiddur is basically because it is easier to Lein from a narrower column and also that the word "Amudim" means standing (taller than wider), and the regular Tikkun for 11 lines is wider than taller so it isn't really called Amudim. I got my hands on some pages of this Tikkun and I am not so crazy about it, maybe I am just used to typical 11 line Megill...
