Well, I emailed to Overwater and got one response where a person told me that he try to find out, if they fit. After that, NOTHING. Well, I did lot of work and found out this string maker called "Pyramid". I contact them and told, what is the problem. They said they can make me strings just as I want them. They will make me one set of flat's and will send them next week. Price is "litle" high but flat's will last pretty long. Actually those string will pay as much here in Finland as they will pay when I ordered them. So, I am happy and even happier, when string will arrive.
